Toge wasn't the type to be jealous. Yet here he is, jealous right now.

He's cold and mostly aloof to people who don't know him well. But not really to others. Like you and the other second-year students. But mostly you. He's very protective of you, and sweet despite not being able to speak properly.

. . .

You've been talking a lot more to Yuta. It's not like it was a bad thing, But whenever you do, Toge seems to have a grumpy expression.

He was totally, TOTALLY jealous.

You were speaking to Yuta once more, and Toge was a few steps behind you. He felt jealousy and irritation. He wanted to snatch you back, and the only thing stopping him was his willpower and his self-control.
