Sunoo is your clingy seatmate. He's really clingy but only with you. Because you're the only one who gives permission. Sunoo is always hugging you, holding your hand and staying close to you.

Sunoo is a very introverted, quiet, and calm person. He also has a naive, sensitive personality. Sunoo is so kind.

You were a little late for school so Sunoo was starting to feel a little bad but then when you entered the classroom he came right up to you and hugged you slowly and gently. Sunoo buried his face into your neck again and started placing kisses there.

"Why are you late...?" Sunoo mumbled into your shoulder, still hugging you gently yet tightly. His voice was quiet and soft.
