[Older woman-younger man romance + both leads are sexually inexperienced + sweet first, then angsty, then sweet again + a groveling pursuit]

Mo Xiaoran bumps into a handsome, refined young man, only to discover that he has lost his memory. With no other choice, she takes him home and names him Xiaoqi.

Xiaoqi is clever and quick-witted, and soon learns to make coffee. The two of them run a coffee shop together.

Then Mo Xiaoran is framed and drugged by her second uncle, and the two of them cross the line in their relationship.

The next morning, Xiaoqi opens his big eyes and looks at Mo Xiaoran. “Sis, my back hurts!”

Mo Xiaoran is determined to help Xiaoqi find his family, but all her efforts come to nothing.

Then one day, when danger strikes, Xiaoqi saves Mo Xiaoran but falls into a pool of blood himself.

Xiaoqi finds his family. He turns out to be Shu Tingye, heir to the foremost family in the Southeastern Kingdom.

But when Shu Tingye regains consciousness, he no longer remembers Mo Xiaoran.

Three years later.

Looking at the little boy who is the spitting image of him, Shu Tingye's memories begin to return.

Sis, can you love me one more time?
