Actually... it may help
Almost no one know what really happend back then
True
Tbh, I think if he does expose the truth, it'll have both pros and cons. Pros would be the fact that they'll finally learn the truth about what happened. Joowon's death wasn't an accident and they'll be one step closer to finding out the culprit. On the other hand, the cons would be that there'll be lots of confusion and there's even the possibility that they won't immediately believe him. Also, Seoha might blame himself even more, since he was originally the one that was being targeted and not Joowon.
i did not consider that but yeah. it could even open old scars for jowoon's family
so, lil brother guy, how much do you want to keep your mouth shut'nt?
