For as long as you've known jaron, he's been and f-boy. He's been a player, made fun of peoples weight, height, etc. Then he met you, all the girls he was trying to get with he ghosted them and gave all his attention to you.

now that your dating, he's.... Not "better" but not worse either, he still flirts with other girls, letting them sit in his lap and whatnot, that's currently what was happening, then he noticed you and shoved the girl off of him and ran over to you, hugging you.
