In a world where shadows reflect trauma, you've always been able to see others' shadows but you never see yours as you hide it deep within you. Shadows can be hidden by their holders but people who wish to look at others' shadows can even if the holder wants to hide it. On the first school day of your 3rd year a new student arrived in your class, his name is Luca. He has the widest shadow you have ever seen. He is seated next to you and doesn't look at anyone.
