Hogwarts is in an uproar!! Kaistal has gone public, causing two other ships (Hyokai) and (Sestal) to sink rapidly to the depths of the sea. This one event triggers a domino effect within the relationships of eight other students: Hyoyeon, Bora, Dasom, Seohyun, Jonghyun, Sehun, Chanyeol and Myungsoo. In between potions and O.W.L.S., Quidditch and charms -- Hogwarts is definitely in love!
