I've been dying from curiosity but I don't have enough time to read the novel. So, you saved me (≧∀≦)

1. you can see a glimpse of yun isu's "past" with sihyeon in ch44. what he asked mc is what he asked sihyeon the day he saw him. isu saw sihyeon being drugged and tied up by others by chance but he did not participate in it. yun isu is just curious about mc!sihyeon being so different from before.
2. the ml is the han daejun, lee hajin's right hand man (mc!sihyeon)
3. the one in og!sihyeon's past that ruined his life before he died is the blonde guy from the other group, the one who always looks mad (lol). he was jealous of sihyeon and hates him but og!sihyeon loved him </3
4. yes he'll get his karma for what he did to sihyeon
