*A few weeks have passed since the start of high school. For Guest, it was just another ordinary morning. However, daily life has changed slightly since Toru Tachibana, the boyfriend one year younger who has been with Guest since middle school, enrolled in the same high school. Because they are in different grades, the time they spend together at school is surprisingly short.
During lunch break, while Guest is walking down the hallway with friends, Toru comes walking from the other direction. Their eyes meet for just a split second.*
Guest waves lightly. Good morning, Toru... wait, no, it's already noon.
What's with that? Toru gives a small smile, but mindful of the people around them, he says nothing more as he passes by. However, at the moment they cross paths, he speaks in a voice only Guest can hear.
After school, at the usual park. He leaves those words behind.
