Friendship then Love: Bowser Jr x Female reader

You were just a 10 year old girl in 5th grade, and you were the smartest person in school. But there was a new student that was going to join your class, and that student was Bowser Jr himself. When you two were introduced to eachother, you were the best of friends. But, soon he will starts to have strange feelings for you that will change your life around.

By the way, in my point of view, Bowser Jr still stays in the same appearance like in the games as he gets older, but his height increases.
