Jae
About
He is Nan Woo's uncle and her mom's half-brother. He moved with Nan Woo and her mother when he was a high school student after his father died. Like Seung Ha, being left alone by his parents (though for different reasons) left a mental scar. Therefore he is scared of being alone. He is as beautiful as a woman, and has no problem finding girlfriends. But they leave when they realize it doesn't matter to him who he is with, as long as he is not alone. He sees Hyun Ho only as a friend as he is not interested in men, but eventually agrees to a relationship when Hyun Ho explains how much he needs him.
