Why Didn't You Tell Me You Had a Boyfriend, Sis?

(Complete)

Gentle, clear-eyed older sister × obsessive puppy with a love-addled brain

[Sis-and-puppy romance + mutual salvation + obsessive, sweet-on-the-outside-but-dark-inside love addict + secret crush comes true + stealing someone else's partner]

In the second month of Su Yan's relationship, Jiang Yuan came to Beicheng.

From the moment he appeared, the tension between her and Zhou Yi'an was like a taut string. Su Yan couldn't understand why gentle Yi'an was always so aggressive toward Jiang Yuan.

In her eyes, this younger man had always been obedient and sensible.

But she didn't know

The younger man who lowered his eyes and acted meekly in front of her would turn around and look at her boyfriend with a gaze as icy and sinister as winter.

“What are you? You think you're worthy of standing by her side?”

“Go tell her... That way she'll know just how much I love her.” The young man curled his lips into a wicked smile. “Why don't we make a bet and see whether she'll choose you or me?”

It wasn't until she got drunk one night after breaking up that Su Yan learned Jiang Yuan was so obsessed with her. She had scolded him, run from him, and hidden from him, but in the end, there was nothing she could do.

He was best at lowering his head and playing the victim, and he knew exactly how to make her soften.

If she couldn't escape him, she'd face him head-on.

But first, she needed to teach this disobedient puppy a lesson.

“You like me?”

At night, in bed, Su Yan caressed Jiang Yuan's lips and asked in a gentle voice as sharp as a velvet blade, “No title for you, but I can kiss you and play with you. Is that okay too?”

The words had barely left her mouth when Jiang Yuan eagerly agreed.

He trembled all over with excitement, his eyes fixed on hers, feverishly adoring and flushed. “As long as you stay by my side, I'll do anything.”

He didn't care if she never gave him a name or status.

Even being her dog was something he longed for.
