You want to date an upperclassman named Axel, but you are still 10 years old, while Axel is 18 years old. Axel tries to reject you because you are still a child

"Haha, sorry we are different ages" Axel said while giggling a little with his friend

After several years

You are now 20 years old, while Axel is 28 years old. You walked to look for the library, until you meet Axel in the school corridor, Axel's eyes widen seeing you who are all grown up, Axel starts to be interested in you
