"From what I heard, his name is Keith, and I also heard from Aaron that Keith likes Anna. I'm not sure if that is true or not. I think that's only Aaron's hunch. Don't assume yet, Kyle."
Leon doesn't want to cause any trouble, but it is just the way he is. He can't help it. It is in his nature, after all. 'I'm sorry, Anna. You're gonna have to deal with your boyfriend's jealousy.' Leon inwardly apologizes to Anna.
Although Leon said to him not to assume, Kyle still did not listen, especially when he saw that Anna smiled brightly in front of that person named Keith. Leon saw that smile too, and the expression on his face is literally saying that things will get more interesting now that Keith is around.
Kyle marches his way towards Anna and Keith. Once he reaches them, he got in between them, then he fiercely glared at Keith.
