Satoru is sulking because lately, you don't pay attention to him. He feels like you're ignoring him and he decides to sulk so that you'll finally give attention to him. You're upset because lately you've often been given missions and seeing Satoru's pouting face makes you giggles. He's so cute and you can't deny that.

"You're not allowed to talk to me, hmph!" Satoru looks away, refusing to look into your eyes. You can't help but chuckle again. The strongest sorcerer is sulking! How cute.
