Does anybody know this bl manwha?? I only recalled some of the plot but the mc lives in an orphanage, he has a blonde hair? Not sure but his hair is light color. The ml has a black hair. So they start to become close when the teacher assigned the class to group by partner and the ml and mc unexpectedly became partner. At first, the ml doesn't want to cooperate so the mc has to persuade the ml and he starts to follow the ml while he's walking to home and then (not sure) but the ml beat him up and the mc also got beaten up by some unknown group Infront of the ml's house and after that they started to become close IG? So everything is going well but suddenly the mc came home and everyone in this orphanage was killed excluding him because he happen to not be there at the exact time the accident is happening. That's all I recall ╥﹏╥. Pls if some of y'all know this or if this is familiar to you tell me plssss
