Aunt Xiangzi, how did you manage to live?

"Aunt Xiangzi, didn't you pass away?" Ruo Yexiao—Mu's adopted son, a prominent celebrity, and the most anticipated idol of the new era—finds himself traveling back in time to his mother's high school days. There, he comes face-to-face with Toyokawa Shoko, a woman long believed to have perished in his own timeline. In Yexiao's memory, the legendary Aunt Xiangzi met a tragic end shortly after her band disbanded. Like a falling whale sustaining an entire ecosystem, her passing had served as the emotional catalyst that drove the group to the pinnacle of the music world, carrying her final wish with them. So, what on earth is Aunt Xiangzi actually doing right now? And what in the world is a "Mother Hen Card"? Determined to rewrite history, Yexiao vows to save his mother from a lifetime of regret. They all swore to be in a band together forever! And if this "Mother Hen Card" dares to try and steal Aunt Xiangzi away from his mother and the rest of the "aunties," he'll just have to steal the Mother Hen Card away first. However, as Yexiao gets closer to these girls, he begins to realize that these future "aunties" are nothing like the dignified figures he remembers from his childhood stories...
