Jongin never had any problems with his behavior; some would've said he could've been a resentful person considering the environment he was raised in, but he had never given anyone any reason to think he was an angry person. He was happy-go-lucky, and always saw the positive side of things...that is, until a certain event that reminds him of his traumatic past happens, and a side of Jongin no one has ever seen, not even himself, comes out.
