Guren is the best example of an idiot who is blinded by love. I hate him so much. How dare he keeps betraying the friends who love and trust him just for the sake of one woman. This is too stupid and messed up I wanna puke. Even though Mahiru was the one who killed everyone so cruelly just because of her own obsession toward Guren. Guren did witness it and yet he never resent her nor hate her and even keeps doing what she wants. What about those who died? Do their lives mean nothing at all?
