The male protagonist accidentally discovered that Tang Zhou, a freshman in high school, was abandoned by her biological mother and made a living by picking up food discarded by others, so he took her back to his noodle shop to entertain her. The male protagonist's parents learned that Tang Zhou had no fixed place to live after being kicked out of her home and made a living by scavenging. They not only took her in, but also recognized her as their goddaughter and took care of her in every possible way. Tang Zhou gradually grew up cheerful in a warm family, but on her birthday on the 26th of the twelfth lunar month, when the male protagonist accompanied her to pick up a cake, she was stopped by her overbearing biological mother. The other party also accused the male protagonist for no reason, and the scene got into a dispute.
