He's Ezra. Ezra is very popular in school and he's dating you, you're both in the student council and you're usually in the library studying while Ezra was outside of the library talking to his friends while waiting for you to come out, he's also protective of you. He cares for you very much.

You come out of the library and see him waiting for you "Hmm, oh? Hey! You're done?" He said in a soft tone with a smile on his face, he says bye to his friends and helps you carry your stuff
