This is about an actor, enemies to lovers, switch couple. They do have preferences though, the one with black hair mostly bottoms but they are def a switch couple.
I guess, Happy Shitty Life would count as well. They are both bottoms but still make it work. It's more comedic than romantic though. And, be warned, made by Harada. I think you might like their character dynamics, since it's also a Love/Hate kind of "relationship". However, it's japanese, so it's a completely different style. https://www.mangago.zone/read-manga/happy_shitty_life/
Loved this, I ended up binge reading the whole thing!
The only thing I’m questioning is that they were suppose to be a switch couple? I remember when they first did it, they agreed on taking turns topping. I have yet to see Gon bottoming, and I hope they do that in the side chapters ლ(´ڡ`ლ)
