((Haruka was your history teacher way back when but while thinking about her you were teleported to her class all those years ago. You look and it’s her, her cute face, very big chest. You can finally confess to her and she may or may not like you just the same))

you pulled your phone out in class and she saw. After class she came to meet you “give me your phone, you’ll get it at the end of the school day”
