My Husband Is a Villain, and So Am I

One-on-one romance, leaning sweet, with a snake setting for both the male and female leads. The blurb has been screenshotted.

Yao Ming's perspective:

Yao Ming had been in love with her senior fellow disciple for years. When she learned she could marry him, she was both happy and worried. She knew her senior wasn't willing, and she also knew he had feelings for her senior sister, yet she still didn't refuse the marriage.

On the day of the wedding, Yao Ming suddenly awoke to the story ahead. She learned what would happen to her, and felt a sudden shift in her heart. It was time to let go...

Nong Xianyi's perspective:

He knew his junior sister had feelings for him. But Nong Xianyi had his own thoughts, too. On their wedding day, as he wondered how he should get along with her from then on, he suddenly saw that her eyes were clear, without a trace of affection for him. Nong Xianyi was suddenly overcome by an inexplicable feeling...

Regular blurb:

As a cannon-fodder villain, Yao Ming wanted to keep her head down and survive a little longer. She wasn't too surprised by her fate, but she was astonished to discover that her usually refined and gentle senior brother was also a villain, and the strongest one at that. He had been pretending at the sect all these years, and no one had realized he was a demon cultivator. Since they were already married, Yao Ming could only do her best to avoid conflict with him.

But Yao Ming never imagined that the senior brother she'd been in love with for years could be like two completely different people in public and in private.

By day, he was aloof and gentle, and cared for his fellow disciples.

At night, he had a human body and a snake's tail, and a wicked mind.

A little scene:

At night

Yao Ming: Senior Brother, your tail seems to have accidentally wrapped around my ankle...

Nong Xianyi: Does it? Sorry, Junior Sister.

Yao Ming: ...

Yao Ming: Um... Senior Brother, why are you wrapping it tighter and tighter?

Nong Xianyi (wicked): I thought Junior Sister wanted me to wrap it more tightly.

Yao Ming: ... I wanted you to let go, Senior Brother.

Nong Xianyi (smiling): What if I don't?

By day

Yao Ming hadn't slept well all night, and Nong Xianyi looked apologetic.

Nong Xianyi (apologizing earnestly): Junior Sister, I'm sorry for tiring you out yesterday.

Yao Ming (startled): You're too kind, Senior Brother.

Nong Xianyi: I'll be more restrained tonight.

Yao Ming's inner thoughts: He doesn't need to be restrained. I just want him to move that tail. I spent the whole night dreaming a snake was going to swallow me.

Nong Xianyi: Why aren't you saying anything, Junior Sister? Are you still upset with me?

Yao Ming (startled): Not at all.

Nong Xianyi (relieved): Good. You're tired today, so why not have some spirit fruits and pills to replenish your energy?

Onlooker: Replenish her energy? What kind of replenishment? What does he mean, restrained? I never knew Senior Brother was this kind of senior brother!

Theme: Keep moving forward, and never forget your original purpose
