Because that idiot Park Chanyeol accidentally burnt their school down in an incident involving uncooked noodles and an aerosol, him and his five kinda nerdy friends have to transfer to a new school across the city. Baekhyun takes an immediate disliking to the clumsy nerd and most of his friends at first but due to unplanned circumstances unlikely romances blossom and I think everyone gets their happy ending really.
