Comment by Anhgi on Jinx - Chapter 76

I was thinking, Jaekyun's mother left when he was little, most likely she rebuilt her life or so I imagine, it wouldn't be crazy to think that she had other children or at least one who could be "papita" and he knows that Jaekyung is his brother that's why he became interested in BOXING to be close to him, that's why he seemed very interested in Jaekyung... besides he has a certain resemblance to Jaekyung
