I am actually looking for a novel but I forgot the title and I actually didn't finish that story. I think it is a rebirth or possibly a transmigration BL story (I kinda forgot). In the first life, MC was actually a lost young master who was found but his biological family did not accept him and doted on the one they adopted. That person was actually very savage and was the reason why MC was abused and died in the first life. However, in the second life, MC decided no more and wanted revenge. Except his brothers were also reborn. Turns out the adopted brother was the reason for their family's demise and when they were reborn they started doting on the MC like crazy. That's the only thing I remember. If you find it let me know. Thanks, everybody.

After searching with Series Finder, I found a possible candidate: After The Vicious Cannon Fodder Was Reborn
