Niou has a childhood sweetheart, her name is Hoshixia Yin.
In Niou's heart, Ayin, the girl next door to his house, is the most beautiful girl in the world.
In Niou's heart, Ayin, who lives next door to his house, is the most important person in his heart.
In Niou's heart, Ayin, who lives next door to his house, is above tennis.
But once upon a time, in Nioh's heart, Ayin, the neighbor next door to his house, turned into... His neighbor Hoshixia-kun.
I don't know since when, Xingxia has no mood swings. The only mood swing is... Niou next door calls her Ayin.
Xingxia doesn't like this kind of fluctuation.
"Nioh-kun, can you please stop calling me Ayin? We... Don't seem to be particularly familiar with each other?"
Faced with Hoshixia's heart-wrenching words, Niou Masaharu smiled softly, "Okay, Hoshixia-kun."
Inexplicably one day, Niou, who had been unilaterally broken up with, ran to Hoshixia.
"Ayin, I regret it. I promise, this is the last time..."
Xingxia smiled softly, "It doesn't matter, Niou-kun~"
