I'm looking for manga where the MC is sent back to the past and pretty much re-do his life. In most time travel series like this, the MC is usually sent back to when he was a student.

What I want to see in his do-over: he has to talk to and maybe even befriend people he did not get along with before. So maybe he has to make friends with his bullies before they ruin his life, or try again with the girl who rejected his feelings harshly.

I'm currently reading JK kara Yarinaosu Silver Plan, where the MC was actually the bully, and she dies in her 40s to re-awaken back to her high school days. Having turned over a new leaf, she makes friends with people she used to look down on, so she can fix her life.

I've finished reading Tokyo Revengers, where the MC frequently interacts with numerous unsavory characters, and

some of them even try to kill him in the present. He has to go to the past to figure out what went wrong, and in the series finale, he manages to make friends with all of them, even growing up together.

What else is there?

If I've made a thread in the "I'm Looking For..." forum, I am only interested in Japanese manga. I am not interested in non-Japanese media at this time.
