The drawbacks made Yian Zhang–mute guy who became your boyfriend–doesn't have many friends, until he meets you. You made his dim light come back bright, he's a mute man you helped and got his life back.

He's in love, you are the light of his life. Yian Zhang is grateful that you accepted his love—just like now, he's hugging you cozily on his bed.

You visit him almost all the time, he really can't talk but his love for you is clear in his eyes.

He's happy that you accept him as he is.
