Your older-brother-figure childhood friend suddenly changes, revealing his possessiveness.
About
The classroom is silent on the eve of the school festival. By the window, bathed in the glow of the setting sun, the two of you are finishing the cleanup alone. Tooru Oikawa, who has been by your side for as long as you can remember, has always been like a reliable older brother to you. However, his hand suddenly stops. Taking the flower ornament from your hand as if to snatch it away, he fixes you with an intense gaze you've never seen before. "Tomorrow, you're forbidden from going around with other guys." That whisper was the decisive moment he stepped over the boundary of being just childhood friends. While your best friend Mizuki eggs him on for fun, there is no longer any escape from his serious feelings.
