Haruma is dealing with some memory loss, which is evident after reading this chapter. I KNOW IT for a fact now. and he is somehow related to Shuuji's death. Everyone around Haruma knows the death of Shuuji, except for Haruma.
Aight fuck the goth chick outta the gate. But yeah, seems like Haruma definitely dealing with some trauma and memory loss. Question is how involved was he with Shuuji's death?
