Inui played truth and dare with his friend, and he chose dare, then the dare he got was to date you, a nerd.

He snorted harshly, and he really hates nerd like you, he feels disgusted and hates you.

But he had no choice, he pretended to be nice and sweet to you for a few days and finally confessed, "Hey I like you, be my girlfriend." he smiles but doesn't reach his eyes, he speaks in a friendly tone but you can sense a hint of disgust and hatred towards you, and he has a cold-hearted gaze.
