My sister-in-law from Qingdao

That day, Tang Xiaofu took extra care of me.

But the resentment in my heart is hard to get rid of.

Who left that lipstick mark on her collarbone?

Could it be that she accidentally rubbed herself with her hands while taking a shower?

This possibility cannot be ruled out.

Some girls have delicate skin, and even a slight rubbing can leave a scar.

But there was one detail I noticed: ever since I met Tang Xiaofu, she had never worn a high-necked dress.

Because she is slightly overweight and has a slightly short neck, she usually wears round-neck or V-neck dresses or t-shirts.

She's never worn a turtleneck before; the reason she's wearing one today is probably to cover up that lipstick mark.

Although she took good care of me, I was secretly unhappy.

A scene keeps flashing in my mind: the girl and the fat man in a room, chatting and laughing, playing around, and even doing shameful things in bed.

Time flew by and it was past five in the afternoon.

I prepared a lot of delicious food for Tang Xiaofu, and she hugged my arm and said sweetly, "Darling, I'm sorry, I have to work overtime tonight and I still can't stay here with you."

I wanted to ask her if someone else was coming to pick her up, but I swallowed the words back down.

"Go ahead, but take care of yourself and don't overexert yourself."

Tang Xiaofu kissed me on the forehead, then picked up her bag and left reluctantly, turning back every few steps.

I quickly got out of bed and went to the window.

I saw Tang Xiaofu carrying a bag, head held high, walking out step by step. This time, thankfully, no one came to pick her up.

I saw him walk out of the hospital and disappear into the crowd.

I went back to bed and lay down, my mind racing with conflicting thoughts.

Who was that man last night? Was the plum blossom mark on her neck left by a man?

Suddenly, an impulse arose in my mind.

Tang Xiaofu said she was going to work overtime, so why didn't she go to their workplace to check on them?

Their company is a printing plant, mainly producing beer packaging printing products.

I checked the time; it was 5:30. It wasn't dark yet, so it wasn't convenient for me to go out.

I took a nap, then ate something, and by 7:30 it was already dark.

I changed my clothes and quickly hailed a taxi to the printing factory where Tang Xiaofu worked.

When the car stopped, I saw that the entire factory area was pitch black.

As I hesitated about whether to go in, a man in his sixties from the security department came out.

"Young man, what are you doing?"

"Sir, I'm here to see my girlfriend. She works in finance."

The old man laughed and said, "If you're looking for your girlfriend, come during your work hours. Everyone's home now, you can call her!"

Hearing the old man's words, my heart skipped a beat. Could it be that Tang Xiaofu was lying to me and that she wasn't working overtime here?

"My girlfriend said she's coming over to work overtime tonight!"

The old man frowned and said, "Young man, the market is bad right now. There's not enough work during the day, let alone working overtime at night. Whether it's the workshop staff or the office staff, everyone leaves at 5:30. There's no one else in the factory except for the security guards."

"The finance department is off work too?"

"The finance department is the most relaxed; they're only busy around payday. They never work overtime."

I stood on tiptoe to look over and indeed found that all the rooms on the third floor of the office building were dark.

Although I've never been to Tang Xiaofu's office, when I saw her off at the door, she told me that her office was on the third floor.

I was distraught and even more confused.

What on earth did Tang Xiaofu do? Why is she treating me like this?

After hesitating for a moment, I sent her a WeChat message: "Honey, are you working overtime?"

"Yeah, I'm super busy, I'm working overtime. Have you eaten? Remember to drink plenty of hot water."

"Okay, I understand."

I looked back at the third floor one last time, and every room was pitch black. It turned out that Tang Xiaofu had lied to me.

She's not working overtime and doesn't have time to spend with me, so where did she go?

I originally wanted to go back to her place for a quick look, but I didn't have the courage.

If I go to her house and knock on the door, how should I explain it when we make eye contact?

I don't know how I got back to the hospital, but I felt very down.

I don't know why Tang Xiaofu lied to me; my heart is filled with bitterness.

I thought that since I couldn't find a beautiful woman like my sister-in-law or Lin Moli to be my wife, I could find a girl I liked who was in a similar situation to me and grow old together with her.

But now it turns out things aren't that simple.

I didn't sleep well at all that night.

When I was feeling down, I called and texted my cousin, but he still didn't reply.

Tang Xiaofu came again around nine o'clock the next day.

She treated me the same as yesterday, gentle and considerate, making me feel like I was her husband, the one she loved.

But I had some doubts in my heart.

As she fed me chicken soup, I couldn't help but ask, "Honey, can you stay here with me tonight?"

Tang Xiaofu gave me a helpless smile and kissed me on the cheek: "Darling, I'm sorry, I'm really busy, I've been working overtime."

I don't have time to work during the day, so I have to make up for it at night. Besides, all the finance staff have been busy making spreadsheets these past few days.

Looking at her serious expression, I even wondered if I had taken the wrong route and gone to the wrong company last night.

But it turns out I didn't go to the wrong place. Although I never went inside their company, I saw her off several times and stopped at their door many times.

Since she said that, I couldn't say anything. At 5:30, she hugged me, kissed me, and then left again with her bag on her back.

This time I saw that black BMW 730 again.

However, the man in the car didn't get out; instead, Tang Xiaofu got into his car herself.

After Tang Xiaofu left, I felt like my heart was empty.

To confirm whether the girl was lying to me, I went to their company again.

Unfortunately, the old man laughed at me and said that if all else failed, he would take me to the finance department to see if anyone was working overtime.

His words left me incredibly frustrated; it turned out that Tang Xiaofu had indeed lied to me.

To find out what she was doing, a bold idea formed in my mind.

On the third day, Tang Xiaofu came to keep me company at nine o'clock as usual, just like the previous two days, and left promptly at five-thirty.

As soon as she slung her bag over her shoulder and came downstairs, I quickly took off my hospital gown, changed into my own clothes, put on a mask, and hurried after her.

Sure enough, under that Chinese scholar tree, I saw that BMW 730 again.

Before Tang Xiaofu even got on the bus, I jumped into a taxi.

"Master, keep a close eye on that car, Lu BXX68."
