Mahoro Haruta is now a successful manga artist, but the hit series that made her career came from the notebook of Shu Yukishima, a high school classmate who died before seeing his work published. When Mahoro is suddenly sent back in time, she gets a chance to face her guilt and try to change what happened.

This first volume leans hard into regret and redemption. Mahoro is not just mourning Shu. She is carrying the weight of having built her success on his ideas, which makes every attempt to help him feel way more personal.

Shu comes across as the creative, inspiring senpai whose presence still shapes Mahoro’s life, while Arashi brings in that grumpy student council energy. He is very much the tsundere, grumpy-cute type and adds some fun tension to the school side of the story.

Mahoro returns to four months before Shu’s death, tries to help him finish his manga, gets pulled into school festival drama, and slowly realizes this is not a one-time miracle. By the end, the story reveals a time loop, raising the question of what she has to do to finally break it.

I like that it mixes heavy feelings with school club comedy and a little chaos. You get manga-making, student council interference, sabotage, clubroom drama, and a really strong undercurrent of grief all at once.

Expect time travel, unresolved grief, guilt, manga club nostalgia, emotional tension, a possible love angle, and a story that feels reflective without losing its sense of humor.

Mahoro’s high school manga club only had two members: herself and Yukishima, the classmate whose notebook later became the foundation for her award-winning debut. Now, with her second series looming and her guilt impossible to ignore, Mahoro is thrown back into the past and forced to confront the choices that shaped her entire life and career.
