Xia Zhi, who died suddenly at the age of 28, unexpectedly returned to the age of 17. This time she has a clear goal: to save her younger brother Xia Xing who suffered from heart disease, to retrieve her shelved dream of painting, and to prevent Shen Yan, a gloomy young man who became a murderer in her previous life but left her a huge inheritance after his death, from going into the abyss.
She took the initiative to get close to the isolated Shen Yan, melted the ice in his heart with hot breakfast and patient legal education, and accompanied him through the crisis of his mother's serious illness and his father's collapse; Shen Yan also quietly responded with actions - helping her block campus rumors, collecting money for her brother's surgery, and giving her painting materials to pursue her dreams.
From the cold stares between the neighbors in the classroom, to walking side by side after the college entrance examination, to sharing the same boat through thick and thin in college, Xia Zhi's "little sun" not only illuminated Shen Yan's life, but also protected each other, and lived the best life together.
