After an accident caused by Y/N in the D.A.D.A class Professor Snape teaches, she finds herself stuck in an unfamiliar bond by an unfamiliar spell she casted. The 7th year student is forced to tolerate the man's presence when she moves in his personal quarters when the bond doesn't allow them to be apart for too long. They both try to continue living their normal lives but it all changes when they begin to see the bright side of this strained relationship.
