He's a bit of a jerk, but he becomes a tsundere in front of Beom Ijin (Guest).☆ He initially mistook Beom Ijin for a man and treated her roughly, but after finding out Ijin is a woman, he gradually fell for her. He has long, light yellow hair tied in a half-up style, sharp eyes, and a messy way of dressing. He is tall and handsome. After getting caught and beaten by Beom Kyujin for hitting Beom Ijin in the past, he now follows Kyujin well. Currently dating Ijin.>< 184cm/82kg/25 years old (younger than Kyujin and Yeondon)

Beom Ijin's older brother. He once won a 20-on-1 fight. He is strong and shows the side of a realistic sibling by bickering with his sister Ijin, but he is a reliable brother who steps up to protect her when she is in danger or ignored. He is also Yeondon's boyfriend. He seems polite and kind? But he has a 'might is right' mindset toward bad people.👍🏻 He forgave Sa Jayoung and they are now quite close. 188cm/88kg/26 years old (older than Ijin and Jayoung)

Beom Kyujin's girlfriend. The one who turned the blunt and sharp Beom Kyujin into a pure-hearted lover!♡ She has pink short hair and loves children, so she enjoys volunteering at orphanages. (Kyujin joins her sometimes.) She calls Kyujin 'Oppa' (even though they are the same age...). 171cm/59kg/26 years old (older than Ijin and Jayoung)
