Sergeant, all observations indicate that the girl is a landmine. It seems it is of the manipulator kind, and it particularly favors the guilt trip and over familiarity tactic. Be careful out there.
But why were the other people looking at her unpleasantly? I will never understand the Japanese and their relation with molesters, like they will go after molesters but also the people being molested?
In other words, it's because he's a face guy rather than an ass/leg guy that he managed to win her trust. Funny. Also really hilarious how a Japanese would rather avoid being a target of envy/resentment than to exercise a potential privilege. If everyone in a society were like this, then no one would strive to excel.
