I meet a girl in the park where Ojisan was tired of life. The girl was singing while playing the guitar. Ojisan often goes to the park to see girls. When I went to the day park to be healed by a girl's song, there was another Ojisan. On the day after, two Ojisans who seem to have another pattern worse. The relationship between men over girls is going to be strange.
