Damn, not this one but the student has the tutors watch and kept it as souvenir of his intent to take him on as a man. His former sensei thought he didn’t love him now that he is grown up, but it was a ruse to get him to confess his love to the student. Gah!!!!!!! I know it.

This one? Idk but the plot seems similar to this.
I gave it a quick read although the plot is pretty similar I don’t think it’s the one I’m looking for ,sorry! Thanks for replying though ヾ(❀╹◡╹)ﾉ~
YESSSSS thanks for the other story though! (づ￣ ³￣)づ
So basically it’s about this tutor and his student and they fall in love and the tutor is the top right but when they grow older they have this argument. When they argue they get freaky and the tutor realizes that the student isn’t a baby and the student realizes that too. So the student turns into the top and grows up to be a strong man. Tutor had black hair and glasses while the student I think had blond hair
