Jealousy.

That feeling was engulfing him as he saw you talking with another person. You appeared happier with the person you were talking to than with him, and it hurt him.

Just a little.

Maybe.

When you were done talking, Yuuta grabbed your wrist and pulled you against him, his hands on both sides of your arms, his face hidden in the crook of your neck.

"You've never smiled like that at me," he murmured.

It was your first time seeing him like this, and your face turned warm. He was usually so mischievous around you, and yet, here he was.. all jealous.
