Based on the popular Vocaloid series, by HoneyWorks, called “Kokuhoku Yokou Renshuu (Confession Rehearsal)“:

Natsuki, a third-year at Sakuragaoka High School, who holds unrequited feelings for her childhood friend, Yuu, who’s in the Film Club. However, instead of being honest about her feelings, she makes him be her confession “rehearsal” partner. Unable to say her true feelings, things start to get complicated when Miou and Akari, who are also in the Art Club, get involved! Will she ever be able to confess for real!?

Zhao Zhitong, who was still in kindergarten, took her parents and a family of three to cross the time-travel. As soon as she crossed, she was kicked out of the house by her cruel step-grandmother.

Looking at the only two cabbages in the family, Zhao’s father and Zhao’s mother looked sad.

Zhao Zhitong blinked a pair of Kazilan’s big eyes, and took out a bag of rice from the space with a bewildered expression…

So, the five-year-old little Mengbao took his parents to start farming, planting flowers, fruit trees, medicinal herbs, opening a shop, opening a restaurant…

The small life is beautiful, but it must be even more beautiful if there is no one who is wholeheartedly seeking her to be his wife.
