Han Xiaole (played by Fu Xinbo) met and fell in love with the beautiful Lv Wen in a cafe in Dali. Lv Wen, a former motorcyclist, suffered brain damage due to an accident and her memory can only last for one day. Han Xiaole racked his brains every day to come up with various ways to please his beloved girl and "re-pursue" Lv Wen. Their love is played out like first love every day. If meeting is not as good as missing, can I love you again in my memory. If Han Xiaole can make Lv Wen's last second no longer a commemoration of the next second one day, then those streets and alleys that they passed by together, and the sunsets they watched holding hands, can they be put back into their hearts. This is the 37th day that Han Xiaole misses Lv Wen. If you forget, it doesn't matter, I remember and remind you. Missing you 37 times is just the beginning, but the story is still going on...
