He's a homosexual so you're scared to leave your son with his homeroom teacher? What crap. Does that mean all te heterosexual teachers shouldn't be left with their students as well? Cause that's what you're saying bro. And justifying that huge bomb he dropped with "Oh. We had a lover's quarrel in front of the child." What the heck are you saying?
Ignoring nonsense like that, cute story.

No matter what, Sangwoo doesn't have to feel apologetic. At all. If he had any issues that did not allow him to attend the group meetings or even contribute to the project, the least he could have done is text the guy he was free loading from at least once to let him know the situation. Why the heck is he making it look like it's some kinda quirk of Sangwoo's? This is plain and fair justice.
Should've stopped the story at the chapter before the marital rape-chapter. That was so unnecessary.
