Tsukkomi-machi no Machino-san

"Machino-san from the swim team always drops by the Domino Club's room, where I'm the only member, before her practice starts. She constantly fires off jokes in a sketch-style conversation, and I can't help but fire back. Back-and-forth banter, teasing words. Conversations full of nonsense... and maybe something more. Every day passed in a flash, yet those summer days felt like they could last forever in that clubroom. But when this summer ends, the dominoes between us will all begin to fall, at once."

"Why did you suddenly start narrating a light-novel-style summary, Machino-san?"
