Lin Xi, a single mother-to-be writer, in order to save her novel on the street, used her childhood friend Shen Juan as "love material", but she fell in love with her while pretending to get closer. When "practical love" was exposed, the unruly boy who had protected him since he was a child used twenty years of affection to prove that from wearing crotchless pants to wedding dresses (suits), all he wanted was Lin Xi.
Purpose: Through the two-way journey of childhood sweethearts, we interpret that "companionship is the longest confession of love." Regardless of gender and form, sincere feelings can always overcome temptations and misunderstandings, allowing fate to last from childhood to the rest of life.
