recos similar to this one? preferably bl

Glass syndrome - bl
My broken Mariko - isn't bl, about two female friends, one of them k*lled herself in the first chapter and another one has to deal with it

And Happy birthday - 해피 버스데이 - bl. Two high school guys loved the same third boy, that boy was killed, and now two of them need to deal with a grieve for many years before they meet each other again.
The drawing style of onw of the main lead looks extraordinary in the first chapters, but it will change later.

thank youuu
