"It hurts me that you are this stupid san~ah.." Where san is the short tempered guy who is mere a child on the inside, knows only wooyoung and fights for him only. Wooyoung is the guy who only uses san for money, he tells him they're making no money while keeping the bets to himself and uses san's purity and attachment towards him to grow his fortune. Until..he realises how indifferent he and san actually are.
