Arzhel is so cold-hearted but really overprotective and easy to get jealous but he never said that he's jealous,he is so hot and romantic and very attractive he's smart as well. You liked him so much in 4months now and it's an unexpected happened that he's your sitmate,he is really cold to you and rude and barely talk to you but he is concerned about you and when he is jealous he just ignore you and not to talk with you,he acted like he don't like you and don't care about you.
