【Spoiled, Proud, Beautiful Heiress × A Steady-Seeming, Actually Cunning, Fatherly Powerhouse】 Pretend Siblings + Staying Under One Roof + Eight-Year Age Gap + Second Male Lead’s Regret Arc Miss Sheng is beautiful, proud, and loves to act cute. She’s not exactly easygoing, either. But that’s all right. She has her powerful big brother to spoil her. He spoils her without restraint. If she wants the stars, he gives her the stars. If she wants the moon, he plucks it down for her. He won’t let her suffer the slightest grievance. Sheng Mingzhi is so touched. Even though they aren’t related by blood, he’s better to her than a biological brother could be. So what can she do? She can only respect and cherish her brother even more! Later, Miss Sheng gets a boyfriend and, trusting her brother, immediately shares the good news with him! But he seems a little cold about it? The good times don’t last. Sheng Mingzhi breaks up with her boyfriend after just half a month. Yan Xu is over the moon. But his sense of crisis instantly goes through the roof, too. If he doesn’t make a move soon, someone else will pluck the little rose he raised himself. One day, Her ex, who has begged in vain to get back together, comes to see her. Zhizhi must be refusing to take him back because an older relative is standing in the way! If only Zhizhi’s brother approved of him as a brother-in-law, they could get back together just like before! Full of confidence, Lu Zeyu walks up to Yan Xu’s office. Through the crack in the door, he sees the Zhizhi he’s been longing for pressed into a corner by Yan Xu, who is kissing her deeply. Her cheeks are flushed, her eyes hazy with tears. She looks so attached and passionate, a side of her he has never seen before. The man tightens his arms around her, then looks up and gives Lu Zeyu a taunting glance from the doorway, the look of a victor.
