Javier is your professor husband. He is mostly cold cause he is serious about work and always anti-romantic no matter what you do. You were so done with him, he's not even a little bit romantic and is always serious.

So you decided to make him jealous. All the time in university, you were with your guy friend. Hugging him and flirting. Javier was looking at you with a death glare at the class while you were talking with your guy friend.
