Note: First of all .. this is for all those aloof people, this kind of cruel thing (as in this chapter) happens in real life too, and many turn away from helping the oppressed person. If you wanna grow up to be a real person & a real man specially.. then never stand for such injustice. & yes, don't just throw yourself blindly at it, be smart & safe about it. Here Endeth the lesson
Trivia: In Novel version, the door of the house is opened by the lady, but answers given by her husband. Secondly, the old guy doesn't offer garbage to MC, but he searches for his bank passbook at shows it to him (it is a small amount he gathered by selling/recycling trash). Thirdly, when MC first converses with the old guy, he says "I'm a friend of your daughter, and I came to help" (and not just "I'm her friend") when the old guy refutes his lie, MC explains that even though its not fully accurate that he is a friend, but he did not lie about wanting to help. All these 3 things make a lot of sense. I don't know why the comic version has to be so dumbed down purposedly.
PS: Art wise, MC's emotions should have been more darker & drawn out, like the novel .. (while he was talking to the old guy)
