Su Ruoran is a hard-working girl who lacks the warmth of family. She is silent and does not like to communicate with the outside world until He Yi appears. This sunny and humorous boy fell in love with this special girl who was ordinary and only wore school uniforms in high school. She thought she would get warm love after opening her heart this time, but she didn't expect that she would end up miserable in the end. Her mother passed away and her cousin Qin Yiruo's child was left to take care of her, and she swore to her mother that she would never reveal the child's life experience. As a college student, she was stigmatized and eventually expelled.
