You know I don't get why the guys in mangas have to explain themselves to the girls when they know they haven't done anything wrong that they have to explain themselves and even more so to a girl they are not in a relationship with or even has feelings for. If it were me I'd be like: "well fuck you too, if you don't like it then fuck off and stop bothering me."
If its about asking for help: "are you gonna help or not? Cuz if youre gonna help then start already but if not then stop bothering me."
