The Cause

Fake siblings | Living under the same roof | Second chances | School romance to urban romance

On the surface: Pure, fragile little white flower x handsome, delinquent young master

In reality: Scheming x devoted

*

Everyone at Yingcai Private High knew Song Ran was rebellious and unruly, wild and carefree, and constantly switching girlfriends.

The new girl, Chen Youyin, had the face of a pure first love, with gentle brows and bright almond-shaped eyes. She seemed like an innocent little white flower who knew nothing of the world.

No one would ever have linked the two of them together.

Until one day after school, Song Ran called out to Chen Youyin.

"Chen Youyin, come here."

His voice was icy. He held a cigarette in his hand, his dark gaze piercing the crowd and locking onto her.

Her classmates were all worried for her. They didn't know when she'd crossed the school's big bad wolf, and told her not to go.

Chen Youyin smiled gently and explained, "He's my brother."

That night, in the quiet room,

Song Ran gripped her chin and leaned in close. His hot breath brushed her cheek as he smiled wickedly. "Just your brother?"

After a moment's pause, he asked again, "Wasn't it you, little sister, who seduced your big brother first?"

Their breakup was ugly.

Song Ran tried every way he could to keep her, using both force and persuasion, but Chen Youyin was determined to leave.

"Fine, go. Chen Youyin, remember this: I'm the one who doesn't want you this time." Song Ran made his threat. "You'd better never come back. If I ever see you again, I'll kill you."

When they met again, Song Ran was surrounded by a menacing aura, the veins in his neck bulging as he pinned her against a hard wall and ground out, "Chen Youyin, didn't I warn you? Are you trying to get yourself killed?"

*The leads' parents never married, and the leads aren't registered in the same household.

*First time for both leads | Happy ending | Both leads have had brief relationships. The hero is a playboy on the outside but a romantic at heart; his mouth and his dick are clean.

*Neither lead is perfect, and both have their flaws. Fans of either lead, beware. Readers with high moral standards, beware.
