Shiela brought her lunch box and walked even faster than Mizuki. Mizuki, on the other hand, walked leisurely, wondering how losing her things gone unnoticed. When they were just few steps away from the closed door of the laboratory, they heard laughs inside. Shiela and Mizuki peeked through the visible glass. There was Angel with two other girls. She recognized them as Alexa and Daniela; both were her classmates, close friends of Angel and always by Angel's side the whole morning. Giggling, mocking, and scrutinizing other people.
