Regret

Jangjun frowned. "What do you mean, um? You did disappoint papa a lot since ten years ago, so what's the problem now, um?" said Jangjun.

 Ryushin was still standing on his knees, his face was downcast unable to see his father's dark glare.

 "Actually ... actually Ryushin has a lot of debt in the school cafeteria, Papa. Ryushin had to work part time, but why did Papa mess up Shin's workplace at that time? So, Ryushin was not paid this month and had to pay compensation for what Papa did. at that time?" Ryushin paused his sentence just to take a deep breath. "So, Shin asks papa to help pay off all Ryushin's debts, huh, Pa?" 

 Jangjun flinched at his poor son's words. Jangjun really made a mistake at that time. He just found out about his Nana who had remarried, and that too with Jangjun's own father. Don't know how devastated Jangjun was at that time that he who never got drunk, so often got drunk to forget for a moment the burden of his mind.
