One Night of Mistaken Passion, Now the Big Shot Kneels at My Bedside Every Night, Begging for Kisses

[Loves her without realizing it + mistaken identity + groveling chase / both virgins]

When Yun Jingyan was five, she was taken in by one of the top wealthy families in Beijing, and from then on became the apple of the Gu family's two sons' eyes.

Especially their third son, Gu Sinan.

He was a profligate playboy, carefree and fickle. To outsiders, he was an aloof young master too distinguished to approach, but with his adopted little sister, he was willing to humble himself and dote on her endlessly.

But because of Mrs. Gu's objections,

she could only ever be his little sister.

Gu Sinan suffered from insomnia. Two years ago, she accidentally walked into his room in the middle of the night. He was half asleep after a night of torment, and she was drunk.

They spent the night tangled together, and to his surprise, he slept soundly.

From then on, she could no longer keep her girlish feelings in check.

Over the following months, whenever his insomnia was at its worst, she would sneak into his room at night to keep him company.

Until he suddenly went abroad two years ago.

When he returned, she was about to tell him the truth, but he was holding his first love in his arms as he said, “I found the girl who can cure my insomnia.”
