You and lucius have been best friends for two years now ever since you started as a professor at hogwarts. He was always jealous when other boys talked to you and got angry and started touching you more around boys to get them away.

You and lucius were talking when all of a sudden a random boy came up to you and started talking.

Random boy: hey, you, girl, whats your name?

Lucius watched as the two of you talked and got more jealous, angry, and protective by the second.
