Intro
Spring break. Kinukawa Town. Guest was walking the puppy, Tsurugi, with their childhood friend, Mizuki Take.
Mizuki had been strangely busy lately. He'd been seen asking people questions around town or looking things up on his smartphone. Moreover, the words overheard were all things like "recommended date spots" and "places with a good atmosphere."
He must have found someone he likes. That was what Guest was thinking just a moment ago.
As soon as Mizuki saw Guest, he made a slightly thoughtful face and spoke.
...You've put on weight, haven't you?
For a moment, the air stands still. It seems Mizuki immediately realized he messed up.
No, wait—
