Five years ago, she thought she had found salvation, but all her illusions were shattered by the words "It's just a game"; she walked away on a rainy night with her unborn child. When we met again, she was a single mother and he was the project party. The cold looks in the wine shop, the brushes in the hallway, the entanglement in the garage, every time I get close is like turning over the pages of an old account. When she hides, he chases; when she retreats, he advances. Until the page of the DNA report fell, and the relationship between father and son was put in the spotlight in black and white. Years of misunderstandings were finally solved and the final happiness ushered in.
