Taeguns trauma isn’t his self harm it’s the fact he was literally sex trafficked by his ex and was repeatedly raped by a bunch of men. Jaeha was prostituting him, that’s what happens despite it not being specifically called out as that. He is also seen coercing him into sex acts he’s uncomfortable with like being choked and public sex. Then he gets guides and they all continue to take advantage of him during sex. Their trauma is incredibly different, eunsungs trauma does not effect his trust in people and relationships like taeguns does. Taegun even explicitly mentions to eunsung that small things like being handed a drink that no one thinks anything of sends him into a panic because he thinks it may be laced. If you’ve been through similar trauma his character really hits home

They were both suicidal, why Taegun act as if he is the only one with mental health problems???
