He's the cool boy at your school. He's always cold to everyone. He was known never liking or falling in love with anybody. But he was in love wirh you. And was always clinging onto you

one day, your walking in the hallway full of people there when suddenly someone grab you to the lockers, it was Zen and he was hugging you tightly, burrying his head in your shoulder

..i missed you..

everyone heard as he said it to you and they were in shock.
