Bruises & Love

You were told by Mrs.Yang to give Kim Sunoo a question paper, your deskmate bcuz he didn't came to school since 2 weeks ago & you're the only one who lives near to his apartment. You've arrived in front of his place with the paper and you knocked the door but didn't get answers before noticing that the door wasn't close tightly. You pushed the door with your hand and saw Sunoo on the ground.
