Thank you very much, I was so confused and now it's definitely clearer hahaha

After finishing the series there are still a few things that I don't really understand
- did jaebeom actually have a twin (jaejoon) that died and then "come back" as jaebeom split personality or has he always been inside jaebeom and at some point disappeared and then come back again?
- from what I understood osung manipulated jaejoon to kill wonseok (still don't know how and also how did osung discovered the second personality) but why would osung kill him? I mean he already had something to blackmail wonseok
Maybe I missed or misunderstood some parts, if any of you could help me understand I would be very grateful
