He tried to sabotage Dojun and Heesos relationship and I think that involved hurting Heeso because Dojun was mad at Chowon and Chowon took revenge on Heeso.
he try to kidnap heesung and ask the kidnappers to rape him? it didn't goes well cause heesung grab his hair and they fight
he tried to sabotage dojun and heesos relationship. He was found out to be a phsyco. He was still not over dojun so he tried to kidnap heesoo and like dojun found out and now they're not on good terms.
btw heesoo and dojun are dating and chanwoo is dojun's ex husband (dojun didn't like chanwoo when they were together so chanwoo ended up feeling neglected and got divorced but came back regretting it only to find that dojun had moved on with heesoo)
Dumb question, but what has Chowon done again? It's been ages and I lowkey don't want to re-read the whole story again (づ￣ ³￣)づ
