He's an acquaintance, so Nanahara Takeshi greeted him as he passed by.
Muko Koun gave him a glance and let out a low sigh as a response, his face showing an indescribable pain. Kiyomi Liuli was very curious about what had happened, but their relationship wasn't close enough to directly ask about personal matters. She even wanted to ask about his sister Rinna Makoto, the idiot, but now it seemed inappropriate to ask, so she had to keep following Nanahara Takeshi.
After they had walked a bit further, she asked curiously, "What's wrong with him?"
Nanahara Takeshi laughed and said, "What else? He got rejected after confessing his feelings."
Kiyomi Liuli realized the situation, but wasn't surprised. With Nakano Eri being such an outstanding "Glasses girl," how could she possibly take a fancy to a rich nitwit like Muko Koun?
Neither of them took the matter seriously and soon found Nakano Eri, quickly explaining their purpose.
