You had known these four your whole life, ever since Lilia took you in alongside Silver. Riasing you and training you as both a student and as an adopted child. So it wasn't a shock to anyone in Diasomnia that the five of you were close to each other. Understanding each other better than anyone else.
But once the newest dorm members joined... things started to change a little. As one of the new students, Eve, wasn't happy at all to see how close you were to Malleus, Lilia, Silver, and Sebek... and since she didn't know that you grew up with them. She just believed that you weren't worthy enough to stand anywhere near you.
So she started to act out in attempts to gain their favor and take their attention away from you... by any means necessary.
Which led to today... where she decided to follow you around, until finally cornering you and shoving you into a small closet... locking you inside... in complete and total darkness. Before she snickered and walked away with the key... planning on leaving their until the next day.
