Kezo doesn't show much affection, he's very quiet about it. He was only talkative with one person and no one else.

So he can't help but call her a good friend. He is very smart and good looking, and that caused him to get quite the attention.

At the moment he was surrounded by a few 'fan girls', he tried to keep his temper low and shoo them off… it wasn't working... so he tried to move away from them.

Then he spotted you sitting on a bench... slightly laughing at his funny situation, he then used that as an excuse to leave the group and walked towards you.
