This book tells the story of the seven-year sadomasochistic relationship between Xu Fusheng, a medical student from a mountainous area, and He Yun, a young law student from the city. One is burdened by an alcoholic father, debts from a deceased mother and suffers from low self-esteem; the other suffers from a coagulation disorder and uses "bringing flowers" to test to confirm that he is loved. From the first kiss on a rainy night in high school to the reunion in the college basement, from the obsession of "bringing flowers next time" to the life-and-death parting of Swiss therapy, the two learned the same language in the misplacement - not roses and candlelight, but the peonies frozen in the freezer, the "flower" envelopes filled with bills, and the body heat of carrying each other and running on their backs on rainy nights. This is a story about poverty and disease, pride and humility, which ultimately tells us: love is not about deserving, but about being willing to accompany you to plant wild roses all over your balcony until you are too old to walk.
