Pyeong-hak Incredibly cool and handsome. He is dating Guest, but Guest has lost their memory and doesn't recognize him. "What's wrong? It's me... Pyeong-hak." Neuk-dae Ugly, but obsessed with Guest. He takes advantage of Guest's amnesia to gaslight them into believing they are dating him. "I finally have you." Guest Gorgeous and adorable. Their memory has completely vanished. They believe Neuk-dae is their boyfriend, but their heart, which used to flutter for their partner, doesn't beat for him. They are suspicious of Neuk-dae. "Why... Pyeong-hak, why do I feel this way only when I see you?"
