Liu Si-jin called Mama Yin 'mother-in-law'. It felt intimate, but it also meant that he didn't have any other thoughts about Yin Mingzhu, which was why he dared to make such a casual joke.

In the original plot, the two of them often interacted like this, but at that time, they were just brother and sister. Moreover, the original owner liked the supporting male lead, Xu Darong, and her high-profile pursuit of love was known to everyone. Naturally, no one took her and Liu Si-jin's teasing to heart.

So the main problem now was that Yin Mingzhu had to jump out of the frame of "Liu Si-jin's sister" and let him realize that she was first and foremost a woman, a beautiful and charming woman. Only then could they have the possibility of further development.

She needed an opportunity.

The handover of work was almost complete. Yin Mingzhu finally had some free time these days. Apart from eating and drinking every day, she also trained. Her slightly soft muscles were a lot firmer, and the lines of her arms and calves were more healthy and clear.

It wasn't that she was bored. As a military doctor, she and a doctor were two completely different concepts.

The so-called military doctor was a soldier first and a doctor second. Usually, they were not much different from ordinary doctors in the hospital. Once the war started or the troops went abroad for peacekeeping missions, the military doctor would immediately be sent to the front line to set up a temporary field hospital. It was no exaggeration to say that they were there to save the dying and heal the wounded under enemy gunfire.

So the original owner chose this job not only because she had excellent skills, but also because she had considerable courage.

After running two laps around the training ground, it was already dark. Yin Mingzhu regulated her breathing as she walked in the direction of the dormitory with Liu Si-jin. There was a thin layer of sweat on her body, and when the night wind blew, she felt cold all over.

"Walking like this, I feel like I've returned to the past." Yin Mingzhu looked at the training ground with a faint smile on her face, as if she was reminiscing.

Liu Si-jin followed her gaze. Several soldiers were still running. The sky was gradually getting dark, and he could vaguely see moving shadows.

He easily recalled the summer when they were freshmen. Yin Mingzhu was still working hard for the college entrance examination. She was so stressed that she couldn't even eat. In order to relieve her pressure, he took her to the nearby park for a run every evening.

At that time, she still had a ponytail, which kept swinging back and forth when she ran, making him want to reach out and pull it every time.

Ten years passed in the blink of an eye.

"Yeah, time really flies."

Liu Si-jin sighed. He turned his head to look at Yin Mingzhu's fair side profile, trying to overlap her youthful appearance back then with her current appearance.

Both of them were immersed in the memories of the past and were momentarily speechless.

Suddenly, a string of cheerful ringtones broke the quiet atmosphere.

Yin Mingzhu was slightly stunned. She took out her phone from her pocket and saw that it was a call from her colleague in the hospital. Thinking that it was something urgent, she quickly answered the call.

Liu Si-jin did not deliberately listen, but she could still vaguely hear a few words. It seemed to be some kind of gathering, and the other party was urging her to go.

"What's the matter?"

Seeing that Yin Mingzhu's expression was a little strange after hanging up the phone, Liu Si-jin could not hold back his curiosity and asked casually.

Yin Mingzhu quickly glanced at him and said, "Nothing. My colleague made an appointment with a few young people, and I want to introduce everyone to each other." She was not shy about such things, and her expression was quite calm.

Introduce everyone to each other … Wasn't that a social gathering?

"You want to go?" Liu Si-jin was a little surprised.

"Why not?" Yin Mingzhu asked in return. She shrugged indifferently and said, "I'm 28 years old, and I can't always be single.

Besides, I'm usually so busy, and I don't have time to make new friends. It's just a social gathering, and it saves time and effort. Maybe I can even meet the right person. "

There was nothing wrong with what she said, but it sounded strange coming from Yin Mingzhu's mouth. After all, she did not look like someone who needed to go on blind dates.

Liu Si-jin said half-jokingly, "You don't have to go to social gatherings if you want to date. Aren't there many handsome single guys in the army who like you?"

"There are people who like me?" Yin Mingzhu smiled faintly and said, "Why don't I know about it?"

There are many things that you don't know. Liu Si-jin thought about the topics that his roommates talked about every day before they went to bed. He could not help but laugh and say, "When did our Second Lieutenant Yin become so unconfident?

Let's not talk about others, there are several admirers of yours in our dormitory. "

"Is that so." Yin Mingzhu nodded. She paused and suddenly looked up at him. "What about you?

Senior, do you like me too? "

Her eyes were round and bright, and they were so clear that they seemed to be surging with moonlight.

Looking into her clear eyes, Liu Si-jin was about to say the word "like", but he suddenly could not say it out loud.

Of course he liked her, but "like" and "like" were different, right?

The "like" he said might not be the same as the "like" she said.

It was rare to see him at a loss, so Yin Mingzhu giggled. She raised her hand and patted his shoulder vigorously. Her posture was very heroic. "Alright, I'm just joking with you. If you don't like me, then forget it. Anyway, there are so many handsome single guys for me to choose from. I don't mind if you're one more."

This joke was not funny at all.

Liu Si-jin cursed in his heart. He pinched her nose hard in revenge, turned around, and ran away.

"Ah, Liu Si-jin!" Yin Mingzhu covered her sore nose and stomped her feet. She was so angry that she called his name directly.

…

It was not until noon the next day when Liu Si-jin did not see Yin Mingzhu in the cafeteria that he realized that today was the day of her social gathering.

Did she really go?

He grabbed the rice in the lunch box and stuffed it into his mouth. He did not know why, but he felt that the taste was not right.

Yin Mingzhu had been smart since she was young. She would not be fooled by any bad boy. Moreover, she was not a casual person.

But when he thought about how she might be chatting and laughing with some strange man who came out of nowhere, his chest felt very tight.

There were so many young men of the right age in the army. Although they might not be as good as him in all aspects, any one of them would not be too bad. However, she turned a blind eye and insisted on going out to meet those guys of unknown origins. What if she was targeted by someone with bad intentions?

Was there something wrong with this wretched girl's brain?

Was he, as her brother, just going to watch her fool around and not do anything?

The more Liu Si-jin thought about it, the more he felt that something was wrong. He put down his chopsticks with a "pa" sound, took out his phone, and dialed Yin Mingzhu's number with a cold face.

The phone rang for a long time before it was picked up. The background noise was very loud and ear-piercing. Even her voice was a little fuzzy. "… Senior, what's wrong?"

It was so noisy. Where did she go?!

A guess flashed through his mind. Liu Si-jin gritted his teeth and asked, "Where are you?"

"What?

I can't hear you clearly. "

"I'm asking you where you are?!"

"… The KTV on Yi Zhi Road."

"Qingtan Cave?"

"Yes, what's wrong?"
