人生逆転～浮気された上に、えん罪まで押し付けられた俺、なぜか学園一の美少女後輩を助けて懐かれる

Eiji Awano, an ordinary high school sophomore, is dating the most beautiful girl in his class, Miyuki Amada, his childhood friend. …

They had been in the same class since elementary school and lived near each other. They were supposed to spend their youth happily and be together for the rest of their lives.

However, Eiji not only skips out on his birthday date but also witnesses Miyuki cheating on him with Kondo, the ace of the soccer team. When Eiji tries to confront Miyuki about the affair, he is set up by his senpai, and Miyuki betrays him, labeling him a lousy domestic violence boyfriend who is violent towards his girlfriend and isolating him from everyone around him.

To escape the cold stares of those around him, he was having a bocce dinner on the rooftop, but when a junior student, said to be the most beautiful girl in the school, was about to jump off the roof, with desperate persuasion, Eiji manages to save her, and his honor begins to be restored along with many students who see Eiji befriend and hang out with her. …

But, somehow, Kondo-senpai and Miyuki go into a hard life mode and start falling down the hill.
