Blurb:
Shen Li sneaks a kiss on her childhood friend, whom she has a crush on, but through a twist of fate, she ends up kissing her friend’s twin sister instead.
Her friend’s younger sister was raised elsewhere from childhood and had only just been brought back to the He family. Shen Li didn’t know much about her.
After kissing the wrong person and getting caught, Shen Li was mortified. She stammered, “Could you keep this a secret?”
The girl pinned Shen Li against the wall and leaned in to breathe warm air against her ear. Shen Li’s ears were sensitive, and she nearly went weak at the knees.
“Sleep with me, and I’ll agree.”
Shen Li: ?
Is she crazy?
Shen Li slapped the crazy girl. Instead of getting angry, the girl smiled, grabbed the hand that had hit her, and pressed her lips to Shen Li’s.
Dou Yuxin and He Jing were biological sisters with identical faces, yet their personalities were polar opposites.
He Jing was kind and gentle, smiling warmly at everyone. She was popular with everyone.
Dou Yuxin was always cold-faced, with an oppressive aura that made people keep their distance.
In the dimly lit sports equipment room, Dou Yuxin backed Shen Li into a corner.
Dou Yuxin: “If my sister knew you had feelings like that, what do you think she’d do?”
Shen Li could barely stand after being kissed. Her voice trembled at the end. “You... shameless bastard.”
Dou Yuxin kissed Shen Li even more deeply, her smile sly.
“Thanks for the compliment.”
After that, Shen Li often kissed Dou Yuxin, on campus, off campus, and even in He Jing’s bedroom.
When things went further, Dou Yuxin liked to gently bite Shen Li’s cheek and whisper in her ear, “Beg me, or I’ll stop.”
On Shen Li’s nineteenth birthday, she received a confession from He Jing.
Holding a bouquet of roses, He Jing smiled gently. “Stop fooling around with my substitute. I like you too.”
Shen Li took the bouquet and watched Dou Yuxin’s back disappear into the bustling crowd. She didn’t look back even once.
Shen Li had always thought that Dou Yuxin saw her as nothing more than a plaything she could amuse herself with.
Until graduation day, when she was cornered again.
“Xiao Li, can you tell me why you rejected He Jing?”
Dou Yuxin had lost the confidence she’d shown the first time. She held Shen Li’s arm, looking uneasy.
Shen Li pushed her away and copied Dou Yuxin’s usual manner, crossing her arms with a cold laugh.
“If you’re asking for something, you should act like it. Remember how you taught me?”
Reading guide/content warnings:
1. This is not a substitute romance. The love interest and her older sister have distinct personalities, and the protagonist knows exactly which one she wants.
2. To be added.
