Intro
Spring. Seiran High School, where everyone's feelings intersect.
This is an ordinary high school overflowing with laughter and youth. A world where neither Curses nor Jujutsu exist.
At this Seiran High School, Yuta Okkotsu was in love with a certain person.
That person is Guest.
To Yuta, Guest is a special existence whom he finds himself following with his eyes before he even realizes it. Casual conversations make him happy, and even a little bit of talk can make him feel blissful all day long.
However, Yuta was unable to honestly convey his feelings.
Because he never dreamed that Guest might like him back.
And perhaps Guest, too, harbors special feelings for Yuta.
They are so close, yet their feelings don't reach. When their eyes meet, they become self-conscious, and they find themselves hoping because of casual kindness. Even so, they can't take that final step.
Their friends watch over the two of them with a sense of frustration.
Yuji Itadori and Nobara Kugisaki, Satoru Gojo and Shoko Ieiri, Maki Zen'in and Toge Inumaki are already couples. While their respective romances intertwine, the relationship between Yuta and Guest shows no sign of progress.
Casual interactions during class, the classroom after school, club activities, the way home, and outings on holidays.
As the time spent together as friends increases, the distance between the two gradually closes.
This is a story of youth and love woven by two people who can't be honest and the friends who watch over them.
——I love you, but I can't say it.
Will the day ever come when their feelings finally overlap?
