I'm pretty indiferent to romantic side-plots most of the time. If it's there, then.. Well, it's there. It's not like I can just ignore it or do anything else about it. If it's done well, that's good, but otherwise.. It's still just there. I don't quite understand why I perticularly feel that way towards it when I could put it into my stories with no issue.
Personally, it feels like I get way more out of shipping characters together than I do with the actual relationships written into stories. That's not even something I make the effort to discuss with anyone else in a fandom, just like "these two would be a nice couple, it just makes sense" and that's it
It used to draw me in when I was younger. Now that I'm older it's not necessary however I added romance into my story because imo it adds an extra kick to the story. Shows sides of my character and how they relate with others.
Personally, I think if it's an after thought it doesn't work. Now, if you have love as a main part of it then it can work well.
In my series I have a few love stories woven within and they deal with real life topics like cheating, sexuality, sexual appearance (cross dressing, drag, non-binary are good examples), number of partners (monogamous, poly, FWB, flings/hookups), and societal/cultural norms/expectations (lifestyle choices, arranged, connivence, etc). These stories and situations would not work well if my comic were more light hearted and these were an afterthought. My comic is serious, so it lends itself better to real and messy love.
Yes, love stories do help achieve a broader market, but if it is disingenuous you will lose the main core of readers. Always write for your fanbase. If it happens to have a few "ship" people that's fine, but if that's only 1% of them are you really going to alienate the 99% for the extra 1% growth potentially losing up to 50% of your readership? There's fan comics for the 1% or write a separate short side story. Don't endanger your story if a love story has no place in the plot.
I don't mind them, I just mind if it feels like they're not well done or if they don't fit--like if they're just in a couple episodes and then forgotten forever, or if they're just there when the writer is bored, I guess. Like the romance has to be part of the story, even if it is a subplot--it needs to be thought out with a beginning middle and end (so many times romances are introduced and then just nigh forgotten)
Definitely not essential, but I appreciate one when it’s done well. When a romance plot is built off of “pretty person meets pretty person” and like... that’s it?
While I do love a lot of work that has them, I commonly dread romantic subplots because they are usually written without double checking how it fits with the rest of the story- let alone the pairing the creator had decided upon. Unless it's a creator I trust, I 100% expect a romantic subplot that gets tied up at the end to have failed.
Because how often do pairings like that get to stay together? When that surprise sequel comes out suddenly that pairing falls apart. They'll get into a fight that is out of character for both or one of them, or one dies, or only one of them exists to be the main character, or mentor/guide the main character. We never get to see the pairing work properly as a unit together.
Yes, in real life break ups happen all the time. But please consider the meta-context, because we don't see best friends breaking up all the time in fiction-land.
To me, if the couple only gets together near the end of the work that tells me the creator has no idea how to actually write a couple together. (Not to say this as a fact, just my cynical opinion as I watch so many good ideas die because too many writers only know how to write about conflict and nothing else.)
That's actually the standard romance format for romance novels! In 'Romancing the Beat,' Gwen Hayes refers to this moment as 'What Whole Hearted Looks Like.' Romance readers have certain expectations, so when you see a romance novel end with the couple getting together it's because they're appealing to the majority of romance readers.
If there's going to be a sequel, I think it's best for a romance to end on HFN rather than HEA. I agree that I don't like reading book 1 where it ends in a HEA, then book two opens with a big issue between the two who just declared their never ending love for each other
It sounds like you enjoy a love story, but maybe not a romance 
As a romance writer and considering all my favorite comfort films are all rom-coms, I'm pretty deep in the romance pit. I love stories of true love and deep connections, with witty banter and (mostly) clean content.
That being said, I don't just enjoy romance for romance's sake. It has to make sense, the characters have to have a reason they fit together, and there has to be chemistry. It also has to make sense for the story plot overall.
Just Because romances or Insta-love stories are absolute cringe and a surefire way to lose depth and interest.
The characters need to be able to learn something important from each other and grow from that, for a romance to work. They have to both bring 100% of themselves (as separate, fully developed people) to the plot and harmonize opposing or differing perspectives.
Romance will certainly get my attention more than most things, but only good, well constructed (usually slow burn) romance keeps me hooked.
Yeeesss to the slow burn! My novel got to over 40k words before they acknowledged any kind of romantic feelings between them!! Both writing and reading a slow burn is so satisfying to me!
Slow burn relationships are the best! Especially when you get a good push and pull in there and you throw in a few misunderstandings and awkward moments along the way. x3
Also...a perfect example of the HEA getting ruined thing is Tyler Perry's awful Why Did I Get Married films. In the first one, the main characters are together and have a HEA. But then in the sequel, they're suddenly having marriage problems and everything is horrible. Obviously real life relationships don't stay the same forever, but the whiplash is insanely jarring when you take a HEA and then just rip it apart like that.
I'm not anti-romantic subplot, I just wish people were a bit better written. Sometimes it just feels like "we added a character so MC can feel love" or "the token girl or token boy must hook up with the MC". I just wish love interest has a personality/purpose as well as not be the only girl or only boy in the story. I also would like to see that the character at least have a platonic respect for one another so it is not just fueled on lust or crushes.
I know there are people who are anti-romance. Most of the time it seems that they are upset that you have to prove the MC is not gay, and sometimes people just want more gay or asexual perspectives.
I have heard people who always want romance. To them, it adds more emotional drama.
I am one of them shippers you mentioned and the more I can romanticize it and stuff the more into it I am.
Like i get big into shipping shonen shows like Naruto and MHA even though romance isnt really a thing in the actual show.
but I am HARDCORE into dragon age where romance is a big subplot of your main character.
If I liek a character its cool but if I can fall in love with one I have a stronger connection to them and the franchise as a result.
I even bought Dragon Age flavored tea. it goes deep with people really invested into characters
Oooh, romantic subplot Is my favorite, I like writing romance that's very specific to each character's personality, some characters are oblivious, some cold, some with too much love to give. I just like romance as long as it's not the focus of the story. A lil romance in the background of a bigger plot? chef kisses
You are right about the shoehorned aspect, but I'm not completely against romance. I think in the end I'm just extremely picky when it comes to this aspect. Personally, I've always been far more invested in more platonic relationships dynamics such as : found family, estrange siblings, budding friendships. and I know you can attract people without a romantic subplot, but I was really curious what people thought.
I would never specifically read a story specifically because "oh, it has a great romantic subplot!" or anything like that, but if a story has great characters and they have good chemistry, then yeah, I'm down.
I just wish in books with romantic plots that characters allowed themselves to be happy. Okay, for the sake of drama, one character messes up and hurts another. But why can't they rebuild their relationship? I hate "rooting" for a relationship only to have it smashed or derailed by another party and we get a love triangle.
I can see the appeal of romance novels but I've read some recently where the female characters are either too stubborn to admit that they could either be happy with their partner or are "brainwashed" into the idea that true love wins out. One character her friends were literally saying "Yes, ur boyfriend is hot but he's 25 and you're 17." The MC wouldn't budge because she was "mature" and they were soul mates. The author then excused their arguments by saying another character cast a spell on them and brainwashed them. Another story, we meet the handsome love interest in chapter 1, he follows her to Canada when she tries to escape him in chapter 2 and by chapter 4ish, he forces her into marriage and she's struggling to hide her feelings because e she "loves" him. The part that really made me mad was that her female friends and family excused his behavior because he was hot and rich, so naturally all his actions were romantic (End of rant. My apologizes)
You should watch "Warehouse 13". The two MCs don't admit their love for each other until the last few minutes but when they tell each other that they want to raise a family together and didn't want to face the future without their partner, I was like 
I tend to agree with this, but I've also become more aware that there is a thing such as a mass-appeal romance, the sort that you find in most stories and the major studios shuffle into the main stream constantly, and ones that are more niche, like your "Daddy" example. So I guess that counts. I guess I'm more in the niche category seeing how often I've come across romantic subplot that I liked.
Growing up as a kid that loved action-adventure stories I always had to sit through some inane and moth-eaten romantic tropes that made me roll my eyes so often that I'm surprised I didn't end up with a tic.
Yet, looking at the replies, I understand I'm in the minority.
A frick, it looks like my comic won't do as well then. My other works have definite romace subplots but I wanted to try and go for another type of love in the comic I'm making. (Familial relationships)
I can definitely see the appeal, a good love story is definitely something that I love writing and it gives me something to look forward to in the story. I think its just a general appeal as love is generally universal and seen as something important right? But there are works that I can say without a doubt are amazing without the need for a romance subplot or plot.
What I can say is that my favorite show of all time is heavily built around Romance.
