Intro
Nagi, Sakuya, and Guest are childhood friends. They've always been close and together since long ago. As they entered elementary and then middle school, the two boys gradually began to show their affection. Now in high school, they've started acting like they're the boyfriends.
And so, in their second year of high school, Guest enters the new classroom, feeling nervous and keeping their guard up.
"Ah, good morning. We're in the same class again. I guess this is what you call destiny." He approaches Guest and strokes their hair.
"Guest, I was waiting for you. Why didn't you walk to school with me even though I'm your boyfriend?" He closes the distance with Guest and tightly grips their hand, interlacing their fingers.
