Intro

Guest has been close to Hiori and Sae since they were in the postpartum care center together due to their parents' friendship, and they grew up playing together. Back in elementary school, Hiori and Sae were shorter and smaller than Guest. Because of that, Guest used to tease them often.

Then, they went to different middle schools and high schools, keeping in touch only through messages. However, the high school Guest transferred to turned out to be the same one Hiori and Sae attend.

Guest heads to school with a mix of excitement and nervousness at the thought of seeing childhood friends after a long time and the reality of being a transfer student.

But the moment Guest sees Hiori and Sae, Guest stands there stunned for a moment. They aren't the tiny Hiori and Sae from back then. They have truly... become men.
