This is the story of Niihama Shincirou, who collapsed after being ravaged by a black company and woke up to find that he had been sent back to his second year of high school. When he wakes up, he finds himself in a time leap to his second year of high school. His high school life …… was gray and shady, but he’s sure he can start over now.
The beautiful girl of his dreams, Haruka Shijouin, whom he met again over time, is even more innocent and cute than he remembered, and above all, she has been staring straight at Niihama.
“I feel like you’ve changed a lot from the Niihama I knew yesterday. You’re still kind, but you’ve grown up, and that’s wonderful!”
If I could change the future, I would definitely save her life after she took her own life after being severely bullied. With the adult mentality and corporate power that I’ve acquired, I’m going to take my revenge on my second youth with her–!



The interaction between Niihama and Shijouin is quite warm.
Their relationship is developing well.
Next is a spoiler, as I've already read up to the 126th chapter on the Kakuyomu site.
DO NOT READ IT if you don't want your mood ruined!! If you're still curious, read at your own risk:
I warned you.
**Spoiler:**
The relationship between Niihama and Shijouin has progressed smoothly and grown stronger. You could even call them a couple, although they haven't officially confessed to each other or made it official. The main reason for this lies with Shijouin Haruka. Haruka is an incredibly pure girl who has never understood the concept of love. Despite reading a lot of novels, which is somewhat unusual but not entirely out of place, her naivety about love is top-notch, to the point where I find it a bit strange.
Up to the 126th chapter, Haruka considers Niihama Shinichiro her best friend—someone more important than a close friend. Although there have been several instances where Haruka teases Niihama with rather destructive gestures, it still doesn't cross the "friend" boundary in her understanding. Lmao
It's quite disappointing, but Niihama himself isn't in a hurry either, as he plans his career future in line with taking care of Haruka.
Their relationship has already been approved by both sets of parents, specifically their respective mothers and Niihama's sister. The only exception is Haruka's father, who strongly opposes the relationship because he is a doting and overprotective father. Lol
So, only Haruka remains unaware of her own feelings. It will need a push to make her realize them.
