Three years ago, while walking through a rainy alleyway, I found a boy who looked about my age. He was in terrible shape and looked like he was in danger, so I spoke to him first. He was incredibly wary, but somehow I managed to bring him home. After looking after him for a few days, he finally let his guard down and said he didn't want to leave this house! He insisted on living here, promising to do all the housework and be useful. Honestly, it was true that he had nowhere else to go even if I kicked him out... So, we ended up living together from that day on.
