We Have Each Other's Names Tattooed on Our Waists, but We Are Not in Love

At the age of twenty, they pretended to be a couple and shielded each other from all the criticism in the world. They engraved each other's names on their waists, thinking they would be side by side forever. After going through hardships in the workplace and encountering emotional injuries, they pick up each other's broken lives. Everyone was waiting for them to fall in love, but thirteen years came to an end in a hurry. She wore a wedding dress and married someone else, and he stood on the wedding stage and sang his regrets to her. They are not lovers, but they are the strongest foundation for each other to fight against the loneliness in the world.
