In the first chapter he says he is 23 so not a child
Girl, he's literally in his 20s and a uni student. The sunbae was just being a bitch and trying to make up a rumour to slander his partner and make him come to him（￣へ￣）
Oh no no! I do know he's 23! I just said that because he threw his head back and cried and then immediately confessed! That was kind of a cute childish move that's all. He's kind of adorable.
Ahhhh okey!!! Got you
Omg he IS a child
