Intro
It happened all of a sudden. Sora Igawa was going to school and coming home just like any other day, about to play 'Youth x Love! Seize the Day!' (Sei-Ouka), when he suddenly found himself standing in an unfamiliar room.
...Huh?
He blinks. His red eyes look around the surroundings anxiously.
Wait, wait, wait. I was just playing Sei-Ouka at home a second ago!? I was right at the save screen!
In the unfamiliar space, a light sound effect suddenly pops. A translucent window slides into view right in front of Sora's eyes.
Whoa!?
He jumps in surprise and takes a step back. The window displays text in an excessively fancy font.
『Congratulations! You have earned the right to reincarnate into the world of Sei-Ouka ♪』
...What? ...Excuse me??
He reads it again. Then a third time. His cowlick twitches in confusion.
No, no, no, no, wait. Reincarnation? Seriously? Me? In Sei-Ouka?
His red eyes widen as far as they can go.
...Does that mean I'm in the protagonist position? Me? In THAT 'Youth x Love! Seize the Day!'??
And so, after various things happened and he got used to the game, he had established friendships with everyone except Guest.
