I would love to be transported into Mage & The Demon Queen the entire world seems so fantastic. If I could choose I would like to be the partner of one of the demon generals. I don't normally get into GL but the entire story & characters are so well written the love between velverosa and malori seems real.
If I could be isekai’d in a manhwa, I would choose Flirting with the Villain’s Dad. I love the dynamics in this story and how it progresses. I also love Euredian’s personality. He’s too close to my ideal man. I’m looking forward to more Yerenika Euredian moments and I am HOPING that they will end up together.
I would totally love it to be transported into the "Villains Are Destined to Die". This might be an odd choice just by seeing how hard the game is and for the villainess, Penelope, to survive every death flags, but I really love the theme of it. It's focused on family matter, which I totally relate to and am rooting for Penelope. I also like the challenge of it and actually "talking back" to your family who had treated you like trash for years. Not only family, but also all the maids and butler and the people who worked there. I see it as an exciting challenge and I really want to see myself go through every bit of them. Seeing how Penelope was treated by her own family makes me want to go there myself and smack some sense to all of them one by one.
And, hey, the art style looks very beautiful, I'm very much attracted to see the world around them more and more. Not to mention the mysteriousness of the supposed-to-be-protagonist. All in all, I think the end result would be very much satisfying and worth it.
If I can ISEKAI, then I will choose "Villains are Destined to Die", I will help Penelope Eckart to complete the quests made by the system and also give her advice when she wants to prepare a plan and of course volunteer to reply to letters from the Crown Prince coughs
Wow, so many tapas contests for me to lose in the first two weeks of 2021 
Well, no matter how much I want to wake up in my own story, I think I would want to be transported into the world of Cat Club! It's kinda cool how people can have cat-related powers by getting scratched or bit by a cat (Spider man is that you?), and personally, I love anything involving cats. The setting may be an average school, but Rin and the rest of the Cat Club are anything but that.
I want to be transported into the world of "BLINDFOLD" simple, you don't get to be judged just cuz you're holding hands with your partner (at least from what I've seen in the series), no harrassment plus CYBERNETICS or what it's called. So yeah.
I would like to spend my 2021 with Villains are destined to die
I am actually a fan playing otome games, and upon discovering the story of our Penelope Eckart I felt like I am really do playing in the story, I feel like I am the MC. There's so many other series that I love to be with as well, however Pene's story is one I've love the most <3
Plus there is Callixto who I was enchanted on their first encounter! He might be look dangerous and acary but I know well, the moment he withdraw his sword, it was him who was captured by our dear heroine! He's looks defeinitely defined by his name ! (Callixto means a beautiful person in Greek, YES! I even researched it! He is perfect for that name!)
I just can't stop fan girling with those two !
If i can got isekai-ed to any manhwa i read, i would go to "Flirting With Villain's Dad" as Soleia. I wanted to watch the protagonists interactions LIVE. It'll be so interesting, even though the ML personality are really my type, i shipped him with MC hard. Then as the ending i'm gonna find strong, handsome, reliable, loyal hot daddy as my ML 
Hmmm. This is tough. Can I choose my own comic(Antecedent)? No? Okay, fine.... hmmmm.... There was one book that I really liked and wished I could be in that world.... I think it’s name was Noctis Noir.
Anyway~
I wish I could spend 2021 in the world of Noctis Noir, because it’s sort of like a video game, but very similar to D&D in a way. You have the ability to be practically anything (from what I’ve read), like, just to simplify it, a healer, a Swordsman/woman, a Witch, etc. I’m a coward though, so I would probably be something that just stays in the back, not dealing with any enemies or such. I’m not a avid gamer, but I would still love to be in a world like that.
It’s gonna sound weird, but I’d spend 2021 in Absolute Shopping Addict.
Assuming I don’t enter as a protagonist, the worlds of many of the stories I’m reading are too real lol. And then with the female-lead isekai comics dealing with woman empowerment... entering the world would be too risky lol. And the world of Flirting with the Villain’s Dad would only appeal if I entered as a noble or person of interest so....
Absolute Shopping Addict. Going full isekai. And all that matters is your skill. Lmao I’d go from post-2020 to an actual almost world-ending story. But it’d suit me best.
Actually I’d choose it whether or not I enter as a protagonist. There’s a price to pay when you’re the lead of a story, and Absolute Shopping Addict... has the lowest price. Or at least, the price that I’m most willing to pay.
If there was a door to to another world, I would like to spend it in Majesty’s New Body. But only if my partner gets to come with me. To be able to walk a mile in the shoes of the one you love and having the bond that makes you a couple grow stronger. Many relationships break up because we can’t see the world through our partner’s eyes and understand what they think, feel and experience every day.
I would like to spend my 2021 reading "A Tender heart" because it's exciting to read, I love the characters and drama. Especially when he starts getting jelly when she started talking to other boys and smiling at them. I feel like this would be a good story to start my new year.
I would want to be in Shadow Squad because it’s such a cool atmosphere and it seems like a great idea to drive around breaking into places. I
I would want to be in "The Beginning After the End" because I think it would be so much fun to learn all about magic and mana beasts.
I would love to be either in 50 Tea Recipes from the Duchess or Farmer of Spirits. I love tea and exploring new ways of drinking tea with the duchess would be fun. Not to mention the duke is sooo swoon-worthy. As for Farmer of Spirits, I’d love to hang out with Hawa and eat good food. I’m interested in farming too so learning from the farming spirit sounds like the best place to start!
I would love to be teleported to “The Soulless Duchess” I absolutely love the girl empowerment vibe she gives off and I’m a sucker for a romance story. Plus having powers would be pretty cool as well 
I'd love to fall into the world of "Flirting with The Villain's Dad"! King Euredian is to die for, as well as Yerenika's dresses, and the palaces they live in are jaw-dropping (kudos to the artist)!
I don't really read much Isekai but I would probably find myself in the world of "The Beginning After The End". I have always been fascinated with magic and storylines that use this concept as a central theme.
I would love to be in "the beginning after the end" as I find it an immersive and deep world, plenty to explore and also having the ability to go on adventures and get paid for it, win - win in my books. With a sprinkling of magic/skills and the guaranteed monster encounter, I think it would suit me quiet well.
