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."
