Can someone recommend me a list of bl manga/ manhwa/ manhua where it's a love triangle involving a girl
* One of them likes the girl and ends up with a guy / tragedy ending
" Both of them likes the girl and ends up together
*Or one of the guy like the other one but that guy likes the girl / Substitute for that girl / even worse

I have read few manga like these troupe soo i need more if any of you have created a list it's for better
