He's Too Clingy

Blurb One:

As the eldest daughter of the Shen Group, Shen Zhixi is cool and aloof. She always assumed the person she'd be matched with in a business marriage would be another cold, untouchable beauty. After they married, they could be a couple in name only, keeping things simple and stress-free.

It wasn't until they met that she discovered he was a young sprout who hadn't even graduated college yet.

His favorite thing was calling her "Big Sis" over and over. He'd ask her to tutor him, work out with him, and play games with him... He was clingy as could be.

Once, she drove him back to school at high speed after his doctor's appointment. As soon as he got out of the car, he suddenly collapsed to the ground with a weak thud. His eyes were pitiful as he said, "Big Sis, you made me feel so awful. Could you go a little slower next time?"

A few passersby glanced over, then indignantly pointed at her and shouted, "Shameless! He's so young, and you're already making a move on him!"

The young sprout protested, "No! I won't let you talk about her like that!"

Shen Zhixi: "..."

Blurb Two:

One day after they were married, the young sprout's friend got drunk and blurted out some top-secret information. For example, he'd won the tennis championship four years in a row, had eight top-ranked heroes in the game, was in excellent shape, and had made billions from his startup...

Faced with her suddenly calculating gaze, he looked bewildered, as if she were talking about someone else.

That night, he got into bed on his own and, as usual, blinked his big eyes. "Big Sis, do you want to sleep on the inside or the outside?"

She said coldly, "Ding Jilin, go sleep outside. Stop pretending."

The next second, he pounced on her and pinned her to the bed. His usual gentle smile was gone, replaced by a deep gaze. In a husky voice, he said, "So this is what Big Sis likes?"

He leaned close to her ear. "Don't worry. I can be whatever you like."
