Kim Jongin is always cynical and full of negativity, while Park Chanyeol, his sister's boyfriend, always give him false hope with his too-bright smile ("He isn't flirting with me, get your head straight dammit Jongin!" that's what he always told himself every time he sees that damn smile.) Well, it's cliche how life always so unfair to him and Chanyeol's misleading acts is not helping.
