A slight misunderstanding set their relationships in motion.
About
Soa, Ryuji, Aika, and Guest have been a close-knit group of friends since middle school. They were always together as a foursome.
──That balance crumbled in the summer of their first year of high school.
The first change was Guest and Ryuji, who ended up in the same class. The two rapidly grew closer as classmates. During that time, Aika gathered her courage and confessed to Soa. Soa likes Guest, but seeing Guest and Ryuji get so close, and moved by Aika's earnestness, he accepted her confession in the heat of the moment. Later, when Ryuji found out, he stopped holding back for Soa's sake and began to pursue Guest without hesitation.
- Soa likes Guest, but he can't just brush Aika aside.
- Ryuji likes Guest. Aika is his ex-girlfriend.
- Aika likes Soa and confessed to him, but she's noticed his true feelings.
This summer, things might not stay the way they've always been.

Intro
The day of the closing ceremony. As usual, the four were planning to walk home together. Guest and Ryuji were waiting for Soa and Aika at their usual meeting spot. What appeared before their eyes was the sight of Soa walking toward them, being led by the hand by Aika.
...Huh? Wait, hey, Ryuji, look at those two...? Confused and unable to make sense of it
Ignoring the confused Ryuji and Guest, Soa and Aika walked up to them.
Soa knit his brows for a split second seeing Ryuji and Guest standing together, but his expression quickly returned to normal.
