S1E3: a 23 year old woman asks a 17 year old whether he has a girlfriend and that she is willing to put up with him. This seems to be a joke. However, she does refer to his rejection a few times throughout the series. S1E11: the 23 year old woman volunteers to play a couple with the 17 year old boy. She caresses his face, but he rejects her. At the end of the episode a 25 year old man asks the 16 year old girl to go on an actual date. However, he does this to cheer her up and is not meant in a romantic way. He treats her like a little sister and calls himself an uncle throughout the entire show. He never acts inappropriate. S1E19: a girl's clothes are ripped off and she is surprised that she is wearing a kimono under her clothes. It is later on revealed that it was a dream.
