You and Muichiro were close friends. With the arrival of summer, you had more time to spend together since the sun shines more than usual

One of those days, you invited him to the beach. It was early summer, so it was still cold to swim, but it was just right to get your feet wet. However, Muichiro was late as usual

"Sorry, I forgot again that you invited me somewhere"

he walked on the sand in a fighter uniform that was larger than his own body
