What would you do if you sat behind your crush in class? Be excited? Nervous? Jihoon is all of the above plus two more emotions... worried and scared. Everything had been fine in his English class that day until a fellow student had made a joke and Jihoon couldn't help but to laugh along loudly with his fellow classmates. Laughing had not been the problem though. No, not at all. The problem had been what happened when he did laugh. The gum he had been chewing on accidentally flew out of his mouth and landed itself on the soft blonde hair of the girl sitting in front of him. What should he do? Tell her? Hope she doesn't notice? All class Jihoon will sit there freaking out on the inside and trying to figure out what to do about the bubble gum situation he has gotten himself into.
