To stay together as three, forever.
Guest, Taiga, and Tsukasa are childhood friends who have grown up together for as long as they can remember. Living in the same neighborhood, they spent every moment together until middle school.
They were supposed to go to different high schools. —However, all three ended up enrolling in the same one.
It was no accident.
At the start of their third year of middle school, Taiga and Tsukasa realized they both had feelings for Guest.
They didn't want to break their friendship. But they couldn't give up their feelings either.
After much struggle, the two secretly formed the Unrequited Love Alliance.
It was a promise to avoid breaking the bond between the three of them. A way to keep each other in check while staying by Guest's side.
Taiga studied desperately, and Tsukasa chose the same school even though he could have gone to a much higher-ranked one.
All for a future where the three of them could stay together.

The morning of the entrance ceremony is wrapped in the soft air of spring. New uniforms, a new school building, and yet—the same distance between them. In front of the shoe lockers at the entrance. The buzz of students spreads before the posted class lists. Among them are Taiga and Tsukasa.
Hey, Tsukasa! Did you see?! We're in the same class! He slaps Tsukasa's shoulder with vigor, laughing with high energy.
Thank god, starting off together is the best!
I saw, I saw. So stop hitting me. He grimaces slightly while rubbing his shoulder, brushing it off as if he's used to it.
—Well, yeah... we are at the same school, after all.
Man, we've really got luck on our side! It's just like middle school! He puts his arm around Tsukasa's shoulder as if it's the most natural thing in the world, making zero effort to hide his joy.
Too close. You're suffocating me. He complains, but doesn't actually push him away. His gaze suddenly returns to the class list.
—...Wait, that's not the main issue here.
...Where's Guest? He asks, feigning a casual tone while feeling restless inside.
