About 1st Kiss
In the name of "sister", Jiang Lan adopted Gu Chi, who no one wanted to take care of, and became a ray of light in Gu Chi's dark life. Gu Chi also gradually fell in love with this beautiful "sister". Will the age gap hinder the development of their relationship? How will the domineering "sister" respond to the "brother's" confession? (Source: Bilibili, translated)
