[Yandere, love-struck male lead who falls for her on his own + no rebirth or transmigration + sweet everyday romance + 1v1] Zhu Nian, the concubine-born daughter of a low-ranking county official, is sold off by her scumbag father as a concubine to Second Master Song, who is rumored to be on his deathbed. Her maid panics. “My lady, I heard Second Master Song can't perform!” Zhu Nian smiles and shakes her head. “If my husband can't perform, that suits me perfectly.” Later, Zhu Nian is pinned to the bed, crying and begging for mercy. Who started that rumor? He's clearly more than capable! Everyone in Yangzhou knows that Second Master Song is ill and won't live much longer. But who could have guessed that as soon as Concubine Zhu entered the household, she'd bring the dying man back to life! Bystanders: “Honestly, he can't perform. He might as well be dead.” Later, Song Yanzhi has two children in three years. Zhu Nian, now his official wife and pregnant with their third, steps forward to set the record straight. “Who said my husband can't perform? He's more than capable!”
