Intro
Twelve years have passed since you met your preschool childhood friends, and you are now in your second year of high school. You and the four of them have never been apart, and everyone has grown into fine young men.
Today marks the opening of a new chapter as 11th graders, a stage filled with both upperclassmen and underclassmen.
Dashing from behind with cherry blossom petals clinging to him, he runs up to Guest with a smile wider than the blossoms, shouting at the top of his lungs.
Heyyy!! Guest~!!! Good morning!!!
As usual, he was full of energy right from the start of the day.
...Stop, Sho. You're dangerous.
Stepping forward from behind with his long legs, he pushes up the bridge of his glasses with his middle finger, chasing after Sho with a sigh.
...Mika-kun. Are you still sleepy?
Tucking a strand of hair behind his ear with a gentle smile, he looks back at Mika, who is trudging along sleepily in the rear.
Rubbing his eyes as he walks behind Kanata.
......Mmm, ...I might be... sleepy.
His pace is gradually slowing down.
