I wasn't going to say anything regarding your “advice,” but after reading this post, now I just have to say what the actual fuck?
So let me ask you this: Do you want to make a GL story because you genuinely like the genre, or do you just want the numbers for fame? If it's the first part, go ahead and don't let me stop you, but if it is the latter, buddy, that's just wrong.
Good for her, Power to her, She definitely LOVES the genre, but do you do as well? Where is the passion? The love? The honesty in all that, if you just chase numbers by piggyback riding a better artist AGAIN? Y'know what you're making? Slop. Slop for people to consume just because it gets you numbers and not because of the love of it. Yes, people crave GL stories, but they want good ones and not slop that feels fake and dishonest.
“If you want numbers, do GL” is just the genderbend version of the crappy advice we had a few years prior. You basically encourage people to make slop just so they can chase the dream of fame, but in actuality, you're hurting the genre's Reputation, every author working with that, and yours because you started it.
Funnily enough, I have a friend as well, and they got over 300k and make a BL. You know what they get? Spoiler alert: nothing.
Neither promotions nor money. Maybe you misread it, or your "Friend” Kate forgot to mention this little fact that she was Staff-picked 5 times or so by Tapas, and maybe got the Boost in stats from that.
So let's talk about your stick-figure isekai:
I asked the 5 people I know who read your story (me included), and we all said it was hard to sit through because it was annoying. Personally speaking, I didn't like it because, besides the concept, it felt like you just relied on references all the time without any original Ideas by yourself. (Hey, look at that reference. Remember this reference? Want a reference to your reference? Is it a bird? Is it a plane? No. It’s a reference!)
So, let me tell you this: If you didn't improve since your last time and just made the same story with just ALL GIRLS ONLY, buddy, you're set for failure. And don't come back here crying, “UwU nobody reads my series because I have low view numbers and my sub count is still the same.”
And before anybody comes at me just because I ranted, here's my advice for OP:
Do what you love the most and connect a lot. And jump over your shadow sometimes, only if you want it and not because you're forced to do it.
