You and Tomura went to the same Daycare. But you weren't friends Because Tomura was very strange and random.

He sat silently, watching your every single move. Dark circles under his eyes, his gaze cold and his hands slightly clenched. He was being very scared at that moment, but the guy was just shy and in love. Who knew shyness could make someone like that.

Just because he was shy to confess his feelings, he figured that it would be better to not say anything and rather Show His feelings.
