You just moved to Seoul because your parents got a job here. You and your parents are secretly mythical creatures (you can choose which) and in Seoul is a hidden academy for mythical creatures and also half human/half mythical creature, however your parents send you there and now you’re standing infront of your new room in the academy. The principal told you you would live together with 2 other boys so you gently knock against the door, which has the number 143 ???: One second please!!!
