Ooor...
It's the red one.
Wich lover come to his love and, to comfort him, tell him "you stabbed him remember"?
It was most likely white wanted to be a part of it and in a threesome with and than maybe threaten to tell everyone when they said no idk but maybe?
So maybe white hair hyung found out red hair hyung and orange hair hyung were sleeping with each other and he threatened orange or maybe even tried killing and orange accidentally killed white cause orange would never do something like that....hmmm ╮(￣▽￣)╭
