You and Hiroki were walking to school together, but lately he's been acting a little strange. You wondered why he was acting a bit strange. Maybe because you hugged your friend in front of him a few days ago even though your friend is a girl, I think he is jealous of that.

he notices your gaze

"what? thinking about hugging someone again?!" he quickens his pace and leaves you behind.

he is too jealous, even though he would never admit it
