None of it is SA mostly. My guy is basically open for everyone, but he was once treated kinda bad, i'd say accidentally by Vercion (Vercion was too lost in his own emotions to notice how bad he was treating Sunwon xd) but in the end they make up so it's not too bad, literally near the end lol. Vercion was forceful but they did frame it as a "worship" so it's really difficult to pin the blame on him and call it sa or rape :/. I don't think Sunwon cares about the sexual part much, if only the pain and fear when bro went berserk

Any SA/Rape ? Just to be safe.
