So Im trying to write a BL story and I basically know what the story is going to be

basically uke has a trauma - and seme is rich they both don't trust people with different reasons but seme fell in love with this shy ass uke (even though shy he has a backbone) ..pretty cliche and basic right?

the thing is I have multiple plot lines in my mind of how they meet and how the seme is gonna find out about the uke's past ,and how they both suit eachothe. its gonna be slow paced on the smut. usually in manga trauma's are fixed with instant sex which im going to avoid in this case and Im trying to make it realistic as possible (still its gonna be fantasy)

what more should I avoid while writing this story?

hope you BL fans can give me some tips

This manga I read long ago, probably Josei.
It's about two female friends that go to a bar.
A is a pretty girl, popular that wants the bartender to like her.
B is a plain girl, A is using her for 'looking better' but she sees her as a good friend. The bartender is interested in B because he knows she is more beautiful. Due to this, later on A ends her freindship with B and they part roads. In the end, they meet and A almost doesn't recognize B because she changed so much.
B ended with the bartender ^
This manga was an one shot.
If you know such manga, please share its title, thanks!!
