He cant tell him the truth, i guess bcause wookyung telling him theres no relationship between them beside their play. Its all started from the safe word “i love u”, i guess heewon already feel if wookyung draw the line from there. Moreover, wookyung easy going with others, like he act that he can easily change his partner if they not satisfy him anymore. And as prosecutor, he cant risk his private life to tell someone who only into play, nothing more than that.
I'm not gonna argue about him not wanting to risk his private life, of course, I understand, and admit that you're right about it, but didn't Heewon already butt in Wookyung's private life a few times? It'd be only natural if Wookyung knew about his job, at least. And again I'm not supporting Wookyung's actions, but it's unfair for him in my opinion.
I guess its bcause of dom nature? That want to control their sub even until the private life or bcause he’s a prosecutor orrr bcause he alrdy have feelings toward heewon (๑•ㅂ•)و✧
If only Heewon told him that he was a prosecutor, maybe things would be a little bit different now. I'm not saying Wookyung would be completely normal if he knew about Heewon's job or anything, but he would be less fucked up, you know what I am saying? I mean, being addicted to that kinda bdsm(or what it's called) is one thing(which is so messed up), but getting drugged and violated by some mfs without even his consent? It's not like Wookyung would announce to the whole world that Heewon is a prosecutor. And he even likes Wookyung, like he could say it to protect him from all that. From what I understand, I can tell that Wookyung learned his lesson and even though I never supported his actions, Heewon is guilty for the half of the matters.
