Baryu

Baryu (his nickname and stage name created by Sia Lee when they were little; his real name is Jinwoo) is a rockstar who is originally a vampire in human disguise. He is the main vocalist of the popular idol group, O'Rnij. Using his popularity as an idol, he takes the opportunity of touching fans to absorb their energy. Baryu is Sia and Sihwan's childhood friend. He is always seen accompanied by Sihwan who serves as his backup energy source. He is in love with Sia but doesn't want to confess at first. When he does, though, he appears to break down and show some of the feelings that he kept bottled up and hidden from Sia due to his fear of losing her. He gets rejected because Sia chooses Jiho over him, and he doesn't take it too well, but gets better after he took some time to heal.
