The outgoing and cheerful Xia Yuanxi has been in love with Yu Qingmu, the youngest daughter of her class teacher who is one year younger than herself, since she was 16 years old.
The two met, knew each other, and fell in love in the second dimension... And then accidentally recognized each other in the third dimension.
At the age of 18, Xia Yuanxi publicly came out as gay. Since then, separation has become the main theme of life. Xia Yuanxi thought that she had gradually forgotten everything about her, and that she had gradually forgotten her.
But when they met again, Xia Yuanxi's heart still beat unconsciously. This time, Xia Yuanxi still mustered up the courage to stand by her side.
However, it seems that fate is playing tricks on people, and an accident separates the two again. Xia Yuanxi and Yu Qingshu both lost their memory, and they no longer seemed to love each other. By the time Xia Yuanxi remembered everything, Yu Qingshu had already disappeared.
I fell in love when I was young, from the summer when I was 6 years old to the late twenties. Xia Yuanxi's sentence "I will never forget you" is not an empty promise, but a fact.
