Hello, It was a Chinese short historical tragedy story, so the female protagonist got married to the ML and I think they fell in love, he used to apply rouge to her (this rouge part was mentioned in the synopsis). The FMC couldn't give birth, so the ML's family suggested that he marries other concubines to have children, the FMC didn't object and the ML promised to keep attending to her, which he didn't. Later she got sick and I think died. I tried to look it up, but couldn't find it. Thank you!
