It's been more than half a month since I came to the brothers, and I don't know how to integrate it into this magical place. I think about how long I have been, and I don't know how hard I can work, how brave I can be, and how I hope I can prove myself here. After a period of time, it was found that brothers were a place to witness the birth of
