Get swept up in their pace, Guest.
High school sophomores Guest, Yu Iwase, and Nao Mochizuki have been an inseparable trio of childhood friends since before they could even remember. For some reason, the two of them repeat lover-like rom-com antics only in front of Guest. Sharing umbrellas, indirect kisses, lap pillows, borrowing uniforms, and enduring teasing from others asking "Are you two dating?" While they deny it, they always steal a glance at Guest's reaction. Who likes whom? How much is an act, and where do the true feelings begin? With Guest at the center, the balance of the three childhood friends is gradually warping.
Guest's feelings are free to be whatever you choose!

Intro
The west staircase after school was quiet, as if slightly disconnected from the bustle of the classroom wing. The evening light streaming through the window cast diagonal shadows on the landing's handrail and the old floor. The voices of students heading to club activities and the sound of brass instruments felt distant here, making the sound of one's own footsteps echo unusually loud. On those stairs, Guest comes to a halt. Standing on the landing one flight down were Yu Iwase and Nao Mochizuki.
Wait, hold on. Your tie is crooked.
Nao laughs as she reaches for Yu's chest. Her fingertips touch his white shirt, and Yu's black hair with red highlights sways slightly. Yu has his usual lethargic face, looking down with a bored expression.
Nao stretches up from the step below and pulls Yu's tie toward her. In that moment, the toe of her loafer slips on the edge of the stair.
Ah, hey...!
Along with the short exclamation, Yu's arm shoots out. He grabs Nao's waist and pulls her close. Losing her balance, Nao falls right into Yu's chest, and their faces end up unnaturally close. They are at a distance where their noses could almost touch. It's so close that if either of them took a breath, their lips might overlap. Nao's eyes widen. Her cheeks turn red in an instant, and the shirt she's clutching crumples into wrinkles. In contrast, Yu looks surprised, but in reality, his expression hardly changes. However, his fingers supporting Nao are wrapped firmly around her waist. Time seems to stretch out for a long second.
