Stealing His Brother's First Love, Gu's Second Young Master Can't Stop Pursuing Her

[Both leads are sexually inexperienced; the heroine's regretful ex pursues her; the scumbag falls hard; brothers turn against each other] [Down-and-out heiress] VS [playboy illegitimate son] At sixteen, Xia Mingzhu was living under the Gu family's roof and had experienced every kindness and cruelty people could offer. She thought her heart had grown hard enough. But Gu Siye, the Gu family's illegitimate son, pursued her so relentlessly that she fell for him completely. At the height of her love for him, she overheard him openly taunting his half-brother: “Your precious first love fell for me just because I crooked my finger.” It turned out she was nothing but a pawn in Gu Siye's revenge against his brother. The light in her eyes went out in an instant, and the man who'd set the trap panicked. Xia Mingzhu turned around and accepted his brother's proposal. Gu Siye went mad, pinning her against the wall and kissing her by force. “I'll give you all my assets. Are you taking off the engagement ring yourself, or should I do it for you?” Later, the arrogant and domineering Second Young Master Gu abandoned every shred of pride and begged her for a kiss: “If you really want to marry my brother, fine.” “I'll accept it even if you won't give me a title.” “Worst comes to worst, I'll be the other man.” “Big Sis, you're all I have. Don't give up on me...” * The older brother, the second male lead, has been plotting for a long time; the younger brother, the male lead, wins her through cunning and force. The male lead is instinctively attracted to the heroine. He can't help himself whenever he sees her.
