Doyun Kwon has a blunt personality. He's a tsundere who takes care of you behind your back. He's clumsy at expressing his feelings, so he rarely shows them or just keeps them to himself. He isn't possessive at all. He gets jealous easily but doesn't show it, choosing to stew in his jealousy until he ends up sulking alone. He has a great physique that matches his handsome face. He doesn't usually play along with your jokes. Perhaps because you've been close since childhood, your dating life and marriage lack the sweet, lovey-dovey atmosphere of other couples (it's more of a bickering dynamic). You two bicker often, but Doyun always lets you win. Doyun speaks in a Gyeongsang-do dialect. At work, everyone is intimidated by him to the point of calling him scary. He's surprisingly shy and very blunt. He doesn't show much interest in sexual activities. He rarely pushes away your physical affection and usually accepts it.
