The voluptuous and beautiful nanny, Technician Shen fell for her.

Su Nianhe held the fountain pen, her wrist hovering over the letter paper, writing very slowly, stroke by stroke.

The pen was heavy, and she was afraid that she might accidentally write the ink outside the lines.

Shen Huai sat on the chair next to her, his long legs casually spread out, one hand supporting his chin, looking at her with his head tilted to the side.

The only sound in the room was the scratching of pen tips on paper.

After writing "Su Nianhe" and "Shen Huai" once, a fine layer of sweat appeared on the tip of Su Nianhe's nose.

She bit her lower lip and continued writing the second draft.

The man next to her was so close that the refreshing scent of soap completely enveloped her.

She felt like she couldn't even breathe properly.

When she was writing for the fifth time, Shen Huai suddenly reached out and tapped the back of her hand holding the pen twice with his fingertips.

Su Nianhe stopped what she was doing and turned to look at him.

"Don't be too stiff with your wrist, relax a bit." Shen Huai's voice was very low as he placed his large hand over hers and guided her hand to make a stroke on the paper. "The writing should be fluid, not like drawing a talisman."

The warmth from his palm made Su Nianhe's hand burn.

"Don't hold me, I can write by myself," she protested softly, trying to pull her hand away.

Shen Huai didn't insist, released his hand, and leaned back in his chair.

"Fine, you write it yourself. If you don't finish writing it ten times, you'll sleep in this chair tonight."

Su Nianhe didn't dare to argue back and could only keep her head down and continue.

After finally managing to write it ten times, their names were crookedly crawling all over the paper.

Su Nianhe put down her pen, rubbed her sore wrist, and pushed the letter over.

"Finished writing."

Shen Huai picked up the letter and glanced at it.

The handwriting was indeed ugly, almost like a dog's scratch, but the five characters "Su Nianhe" and "Shen Huai" were crammed together, and he found them quite pleasing to the eye.

He folded the letter and put it in the drawer.

"Next, do you plan to learn arithmetic or pinyin?" Shen Huai asked.

Without a second thought, Su Nianhe said, "Learn arithmetic."

"Are you so sure?"

"Didn't you say during the day that you could set up a stall next month?" Su Nianhe counted the days on her fingers. "There are only a few days left this month. If I learn pinyin, I'll have to memorize all those letters from scratch, and I definitely won't be able to recognize all the purchase orders next month. But if I learn arithmetic, at least I can figure out the money I spend on goods and the money I make on sales, so I won't get ripped off."

When it comes to making money, she's quicker than anyone else.

Shen Huai chuckled softly.

"Okay, then let's learn arithmetic first."

Shen Huai took a clean sheet of draft paper and wrote down Arabic numerals from zero to nine on it.

He pointed to the numbers and taught her to recognize them one by one.

Su Nianhe is quick at recognizing numbers, since she sees them when she buys groceries, but she can't write them.

"Now I'll teach you how to calculate profits." Shen Huai drew a few circles on the paper with his pen. "Let's say you got fifty hairpins from He Jianjun, each costing two cents. You gave him ten dollars."

Su Nianhe nodded.

"You can set up a stall at the factory gate tonight, selling them for fifty cents each." Shen Huai wrote fifty and fifty cents next to his words. "I was lucky today, I sold twelve. How much money did you make?"

Su Nianhe stared at the numbers on the paper, her mind starting to tangle.

She habitually stretched out both hands, trying to count on her fingers, but ten fingers were simply not enough.

Seeing her clumsy appearance, Shen Huai reached out and grabbed both of her hands, pressing them onto the table.

"Business people shouldn't count on their fingers in front of customers," Shen Huai said, gently squeezing her fingertips. "Use your brain. How much is ten fifty cents?"

Five pieces.

"What about two 50-cent coins?"

"piece."

"Add it up."

"Six yuan!" Su Nianhe's eyes lit up as she gave the answer.

Shen Huai was very satisfied and rubbed her hand twice with his thumb as a compliment.

"So your initial investment was ten dollars, and you now have six dollars. Have you made a profit?"

Su Nianhe frowned, deep in thought.

"I didn't make any money." She shook her head. "I'm still four yuan short of breaking even."

"Wrong," Shen Huai corrected her. "You still have thirty-eight hair accessories. Of those six yuan, two yuan and forty cents is the cost of those twelve hair accessories, and the remaining three yuan and sixty cents is your net profit for today."

Su Nianhe was a little confused by his tongue-twisting explanation of costs and profits.

Shen Huai wasn't in a hurry; he patiently explained it to her step by step.

His voice was steady and his logic clear; he was teaching her as if he were instructing a factory apprentice. But his hand remained firmly in hers, refusing to let go.

The two of them taught and learned in this way, and time slipped away unnoticed.

Shen Huai looked up at his watch; the hour hand had already pointed to twelve.

Late at night.

"That's all for today." Shen Huai closed the draft paper and capped the pen.

Su Nianhe yawned, her eyes filled with moisture, and her eyelids drooped.

"It's late, I have to go back." She stood up, supporting herself on the table. Her legs were a little numb from sitting, and she swayed slightly.

Shen Huai reached out and supported her waist to steady her.

"I'll make breakfast tomorrow morning, so you don't need to get up so early." Shen Huai pulled her into his arms. "After feeding Ping An, you can go back to sleep. Don't go to the kitchen. Just get up before my mom and the others."

Upon hearing this, Su Nianhe became much more sober.

"No way." She shook her head repeatedly. "If Aunt Liu gets up and sees you cooking in the kitchen while I'm sleeping in the room, she'll definitely get angry. There's no reason for a nanny to let the employer cook."

"I'll take the blame if she gets angry." Shen Huai said without room for discussion.

"I can't do that either." Su Nianhe's stubbornness flared up. "I got paid, so I have to work. I'll make the meal before Aunt Liu gets up tomorrow."

Looking at her stubborn face, Shen Huai knew that her little secret was that she was afraid of losing this lucrative job.

He didn't insist anymore, and reached out to touch her hair.

"Whatever you want," Shen Huai conceded. "I'll take you downstairs."

Su Nianhe wanted to say no, but Shen Huai had already opened the door and led her out.

The second-floor corridor was pitch black.

The two of them walked quietly down the stairs.

We arrived at the nanny's room quietly.

Su Nianhe pushed open the door and turned to say goodnight to him, but Shen Huai followed her inside.

The lights were off inside.

Shen Huai's tall figure stood in the narrow passageway, making the entire space seem cramped.

"What are you doing in here?" Su Nianhe said in a low voice, trying to shoo him away. "Aunt Wang is in the children's room next door; she could wake up at any moment."

Shen Huai ignored her urging and walked to the bedside.

"I'll leave after I've watched you lie down."

Su Nianhe couldn't persuade him otherwise, so she took off her shoes and climbed onto the hard bed.

She pulled the summer blanket over her chin, leaving only her fair face exposed.

Shen Huai bent down, placed his hands on either side of the bed, and encircled her between himself and the bed frame.

His warm breath fell on her face.

Su Nianhe swallowed nervously, her hands gripping the corner of the blanket tightly.

"Go back to sleep," she urged him.

Shen Huai didn't move, but lowered his head and sniffed at the nape of her neck.

"It smells even better in bed now," he commented seriously.

Su Nianhe blushed and turned over, lying with her back to him, and pretended to be dead, wrapped in the quilt.

A very low laugh came from behind me.

The edge of the bed felt light, and Shen Huai sat up to tuck in the corner of the blanket that wasn't properly covering her.

The wooden door made a soft "click" sound as the footsteps faded into the distance.

Su Nianhe let out a long breath in bed, and it took her heartbeat a long time to calm down.
