She is a rich girl, quiet but stubborn, who has always dreamed of becoming the bride of her brother next door. However, meeting him was the beginning of a turning point... He protected her under him in the rain of bullets; when he was hit by a car, he hugged her crazily to protect her... She thought that he had been in love with her for a long time, but little did she know that he fell in love with her at first sight as early as the first sight of her! He didn't know where the love started, but it went deeper and deeper. He doted on her to the heavens and hurt her to the bone. He just wanted her to be worry-free in this life!
