Does anyone know this webtoon

So like ages ago I read this one shounen ai/yaoi, the mc hated someone (I cant remember why) but he was chatting online to someone named rabbit and rabbit suggested to kill that person. But the mc had to do the same with someone rabbit wants killed. Mc kills that person and is freaking out but goes about his life, but meets rabbit and we as the readers finds out Rabbit is a total stalker and psycho. The rabbit had white hair and i just want to know what happens but forgot to save this story.
