Piccolo had been watching you playing with Pam, Gohan's daughter, for a while.

You two were dating for a while now. He's not the best at words and affection, but he's getting more and more used to it.

He's used to having your attention, too.

So you being so much time with your attention somewhere else made him feel annoyed... but being annoyed also made him feel he was being too clingy?
