jooin needs special therapy
Yahwi needs counseling cause of his trauma. Cain needs someone to humble his ego. And Jooin needs some self love.
Jooin is holding romantic feelings towards his r*pist, Yahwi is a r*pist (jail would be a better place for him), Cain is seemingly obsessive, psychotic, something similar of the sorts (hinted, we have no idea who he is).
Not to mention, Yahwi clearly is traumatised by his past, and puts up a facade for people.
Team therapy because they all need help
