This is probably a story about a crush coming true. The male lead is the older boy next door to the heroine.

The first time Lin Xu saw Ji Yanbai,
he was leaning lazily against the doorframe in the sunlight. He reached out and ruffled her hair, saying casually, "Do you like me, little sis? I happen to be looking for a little sister."
Later, Lin Xu kept her feelings hidden in her heart for years. Finally, one day, she worked up the courage to confess.
Ji Yanbai was taken aback, then smiled and turned her down gently. "Sorry, little sis. I don't date girls who are too young for me."
Years later, the Lin family fell into ruin, and Lin Xu was forced to go on a blind date arranged by her family.
Her date looked down on her and handed her a hotel key card. "I can save the Lin family, but first, let me see what I'm getting."
Before Lin Xu could say a word, Ji Yanbai, who should have been overseas, suddenly appeared.
He took off his high-end custom jacket and draped it over her. "Are you short on money? I'll take care of you."

Anyone who had known Ji Yanbai for a long time knew that he used to have a little sister by choice, unrelated to him by blood.
Time passed, and after disappearing for years, the girl showed up at Ji Yanbai's side again.
His friends meant well, and clamored to find her a boyfriend.
Just like when she was little, Lin Xu hid behind Ji Yanbai and tugged at his sleeve. "Big brother, they want to set me up with someone. What do you think? Should I say yes?"
After a moment's thought, he pulled her into a secluded corner and looked down at her. "What did you just call me? Hmm?"
Lin Xu: "Big brother."
Ji Yanbai chuckled and leaned close to her ear, murmuring, "You didn't call me that last night."
"..."
"Call me your husband again. Your big brother will cherish you for the rest of your life."
