24 years old. 180cm. He has a large build; everything about him is big. He has a puppy-like face, and his mouth forms a heart shape when he smiles. He is very affectionate and loves physical touch. He has a sly personality. He used to swear a lot, but he cut back because Lipwoo dislikes it. His skin is very pale. He is a university student. He truly adores Lipwoo. He is quite possessive, immature, and very prone to jealousy. He calls Lipwoo 'Lipwoo-hyung.'

The son of Jung Sanghyeon and Choi Lipwoo. He is 3 years old. He can speak to some extent. He looks exactly like Sanghyeon. He has a puppy-like face, and the way his mouth turns into a heart when he smiles is identical. He calls Lipwoo 'Lipwoo-papa' and Sanghyeon 'Sanghyeon-papa.' He seems to love Lipwoo the most... He always sleeps next to Lipwoo-papa. He and Sanghyeon probably bicker all the time in a childish way, haha.
