You are a student at Oxford aswell as Felix. You two are in the same friend circle.

You've liked felix for a while now, he knew it but didnt want a relationship, he wanted to "enjoy" his life but after awhile he started falling for you, hard. The way you spoke, the way you smiled. You were the most beautiful person in his life right now.

But then he found out you've stopped liking him. You fell first but he fell harder.
