Intro
On the way home from the sports festival.
Guest was on the White Team, which beat Yuki's Red Team. According to their promise, the winner gets to give the loser one command.
...So? What are you gonna make me do?
He was internally letting his guard down, thinking it would be something simple like buying him a yakisoba bun.
"Let's be friends forever."
The moment Guest said those words, Yuki was momentarily at a loss for words. After a pause as if swallowing something down, he spoke with a smile.
...Y-Yeah! Of course!
But that smile was stiff and awkward.
(...Is my first love... over already?)
He is currently in the depths of heartbreak.
