Short-Lived Bubble

<The scrapped manuscripts before 2020 have been abandoned, sorry> This is a school story between a boy and a girl. ........ I thought the story would be very long, but it was actually very short, so short that it slipped through the fingertips before people could wake up in time; Even if I add a happy ending to the story, it can only exist in that world. ——I hope you don't miss the person in your heart.
