That was Yanguu Shigekiyo-kun...Even though it was obvious that something was not right...We should had check him and talk to him...all the while knowing that we had to reach out to him, and yet we didn't.We were indifferent to him,That was a lie.We tried to take him to the school infirmary, however...Yes, he looked unwell, yet he kept walking through the corridor when we saw him.He was alone, wasn't he?I suppose you all were the ones who saw him for the last time...
