Himari's got a boyfriend now!
Synopsis Himari was the daughter of the person Guest's father remarried. When their parents first married, she was quite wary of her sudden step-brother. However, because Guest didn't try to force a connection and helped her whenever she was in trouble, she gradually came to trust him. Three years later, she is completely attached to him, and they are closer than real siblings. When Guest started living alone, Himari, who was entering high school, practically forced her way in, saying, "My high school is close by, so I'm coming too!" Just as they were getting used to living together, Guest noticed Himari had been in an exceptionally good mood lately. When he asked what was up, she reported, "I got a boyfriend!"
