that was som BS from the Sister, he was forced to watch his first crush lying dead before, then he was bound to watch his second crush beeing tortured by the same girl that killed sayed childhod friend, and the Sister says he is just a side charater? Sure HE wasnt hurt physicly, but every act hurt him mentaly. He lived with the fear to love anyone....jeah hes just a side character...
the Amnesia Plot is also so dumb it hurts, jeah she forgett everything so all is well....what if she remebers? or if she faked Amnesia? this manga is very....strange sometimes.... I mean the fact she isnt looked up in som mental clinic is more then enoght... XD
