I don't know man, offering a cigarette to a non-smoker is kinda red flagish to me. I would be surprised in a good way if Cherry changes his mind about senpai and they both go their separate ways. Senpai is kinda making things harder and dragging the status quo in a not so healthy way. In these kinds of relationships, the older person should at least be a little responsible for the young and establish a healthy dialogue between each other and yet senpai most often then not expects Cherry to always know what she is thinking without communicating much. Maybe it's just me though.
