Nekoyashiki Haru, a 17-year-old male, dropped out of school to play in a band. He's blind, drinks a little but never smokes. He loves to draw, though he's not very good at it. After many years, he returned to Shimokitazawa, only to find he'd completely lost his sight. Fortunately, a miraculous pink soft-bodied creature led him to safety, saving him from a treacherous staircase. From then on, he began his life as a staff member at the livehouse called "Starry Sky." ……………When he went to sleep… he kept hearing someone whispering strange things in his ear. Yellow: No need to try anymore, kitty. I'll always be by your side. Blue: Let's just be friends. I can't live without you. Red: I'll snatch you from you, please wait a little longer. Pink: Thank you… Thank you for watching over me. I'll repay you with my whole life… But if you don't accept, I'll go to $^^•$+" (an incomprehensible voice). "What will my ending be like…?" Nekoyashiki Haru couldn't help but wonder, realizing he wasn't the only one in his family.

At the age of twenty-six, Haru, who had been dating Yukino for seven years, finally reached what lovers call the seven-year itch. Their daily lives were filled with endless arguments and boredom over trivial matters. Finally, when Yukino became pregnant out of wedlock, their biggest conflict finally erupted. However, time is a mysterious thing; perhaps the gods heard their prayers. An accident transported the naive couple back to the day they first met in high school. "If it happens again, I'll never date you!!!" "If it happens again, I'll never date you!!!" From their beds in the infirmary, the two gazed at each other, their younger bodies uttering these words. But could it really be so smooth? So, Haru Kasuga and Yukinoshita Yukino, please do it again! !

When I first woke up, I thought this was an ordinary everyday world. Because in my memory, it was a very peaceful world. After searching my memory, I thought it was a mixed anime world. Because in my memory there were people like Yukinoshita Yukino, Sawamura Eriri and others. When I touched the transformation device on the bedside table, I thought this was a world invaded by monsters. I will transform into a lone hero to save the world. When a group of people who claimed to be the Human Rights Security Agency came to me, I felt a little confused. What kind of world is this? When I met the person who claimed to be the president, the confusion reached its peak. "That's right! The president is me, Theresa!" So, is it too late for me to go back now? Let's get back to the point. After saying so much, there is only one thing I want to express. "Sure enough, knights and youth romance stories don't go together." "Amazon."
