One Night with My Husband's Enemy

Her husband's secretary turns up pregnant and names the father. Qin Suyue teaches traditional Chinese painting and had not known about any of it, and inside a short stretch she has lost the life she was living. She meets Cheng Junwen at the bottom of that. He is younger than she is and he is her husband's rival. She takes what happens between them for something brief with no name on it, and then he keeps at it until it turns into something else. He protects her without asking anything back, and through the worst of it he is the only comfort she has. Her family's schemes start surfacing one at a time. With Cheng Junwen behind her, Qin Suyue ends the marriage and puts the family's arrangements out in the open. Old ties between the two of them come out at that point, and she learns the whole thing had been set up long before she walked into it.
