In chapter 1, there's a brief mention about Si Jin proposes to Mo Yeon, but I didn't elaborate it. This is what happened...

Bonus Chapter: Kang Mo Yeon and Marriage Proposal

It had been a busy day for Kang Mo Yeon.

She handled three surgeries, had night shift and her shift had just ended. It was past noon and her boyfriend called her minutes ago, asking her to meet him in their usual place tonight. Si Jin had just returned after a two weeks mission and they met two days ago, rekindling the feelings of missing each other with heavy make out session and toppled on her bed although they didn't do far more than that. Her boyfriend was indeed old-fashioned. She was expecting him to pick her up at the hospital, but the Major apparently changed his mind.

Mo Yeon was thinking a lot after her visit to her mother's house.

What would she do if Si Jin propose to her?

The doctor never really thought about marriage before even though she and Si Jin made a promise in the Urk beach to get married. With their opposite jobs and the little time they could spend together, Mo Yeon often thought how they could make it work when someday they got married.

But, like her mother had said once, Si Jin was the one who could understand her job, just like she understood his. And she would like to believe he was the perfect man for her.

After she arrived at her place, Mo Yeon took a bath, washed her hair, and changed her clothes before riding with her car to the coffee shop. It was Saturday night and Coffee was crowded. She looked around, trying to find her soldier boyfriend among the other customers and almost passed him if he didn't raise himself from his chair.

Mo Yeon stopped abruptly on her feet and blinked when she saw Si Jin.

She had seen him wearing his dress uniform in Urk and he never wore it again during their relationship. Mo Yeon almost forgot how handsome he looked in that uniform.

They stood and stared at each other before Si Jin cleared his throat and smiled slightly. "You're here. I almost thought you wouldn't come to see me."

Mo Yeon also gave Si Jin a smile. "Am I late?" The sight of her boyfriend with his uniform was making her blushed slightly.

The Major laughed. "No, not really." He looked at his watch. "Actually, you're five minutes early."

"Oh..." The doctor pursed her lips. "So, you've been here early too?"

Mo Yeon remembered Si Jin mentioned the time they supposed to meet and when she glanced at her watch, she was indeed early. But, if she was early, then...how long Si Jin had been waiting for her in this place? And wearing his dress uniform?

The doctor may knew a little about the rules and customs in the army, but she knew dress uniform was a formal uniform and she didn't think the coffee shop was a suitable place for Si Jin to wear that.

Some customers glanced at them, especially at the Major, but he didn't seem to be affected by all the glances. The doctor smiled slightly and sat across from Si Jin while the latter sat back on his chair.

Mo Yeon glanced at the empty table in front of her and raised her eyebrows. "You haven't order anything?"

"I was waiting for you," the Major answered a bit nervous, causing Mo Yeon to feel suspicious.

"Are you alright?" Mo Yeon asked uncertain. "Why are you wearing your dress uniform?" She frowned. "Are you having another discipline measure? You just got back."

The Major laughed lightly and stared at Mo Yeon's eyes. "No, it's not. I can wear this uniform if there's a special occasion."

The doctor blinked. "Special occasion? We've met before in this place several times for our date in the weekend, but you never wore your dress uniform."

"It's special occasion for me," Si Jin's eyes didn't leave Mo Yeon's. "This is the thing I wanted to talk about, the one that I mentioned in my phone call when I was on my mission."

"Oh..."

There's something important I want to ask you.

Something important? What is it?

You'll have to wait for next week. It's a punishment for you having day off when I'm not around.

Mo Yen remembered their phone conversation when she was in her mother's house. Well, she didn't exactly have a day off, but changed her schedule instead. And seeing Si Jin wearing his formal uniform was making Mo Yeon felt insignificant.

She only wore her long coat, a pair of flat shoes, jeans, a shirt, and her hair was in a bun.

What was exactly the special occasion and what was the thing he wanted to talk about?

Si Jin smiled slightly and held Mo Yeon's hand, causing the doctor's heart turned erratic. "Kang Mo Yeon, ever since I knew you, you are the important person for me. Never a second I forget about you, even when I was in my captivity."

Mo Yeon couldn't say anything to counter that.

"During my time when I was locked in the basement, I always blame myself for taking you for granted. I felt the same way before I met you, my world turned dark. I promised to myself, if I ever see you again, I will make you happy."

The Major chuckled to himself. "I know I shouldn't have said this, but if you already read my will..."

Mo Yeon froze and Si Jin could see the change in the doctor's posture. He held her hand with both of his hands. "I meant it when I said in the place where you are, it's always bright."

Si Jin's words didn't make Mo Yeon felt happy.

Why was he doing this?

Did he want to...

"Why are you saying those things?" The doctor suddenly asked. "Do you want to break up with me?"

If only Mo Yeon remembered, Si Jin was asking the same question after his mission to rescue her from Private Ryan. And of course, the Major could only smiled slightly with the reverse situation.

"No, I told you, I want to be together with you." His eyes were soft. "I said that multiple times and I still do."

Mo Yeon blew a breath and chuckled. She, too, began to feel nervous. "Then, what is it? Please, don't make me guessing. Is it another mission?"

"Well...sort of."

Si Jin sighed deeply and released his hold on Mo Yeon's hand. After several moments, he pulled out a small box from his pocket and without looking at Mo Yeon's eyes, the Major put the box on the center of the table.

The box was red, not small, but not big either.

Mo Yeon's heart drummed.

Did he...

But, he didn't say anything about marriage.

Could it be another present?

He has given her a necklace with a box too.

"Before you open the box, I want to show you something," Si Jin said and pulled a ring from his other pocket.

He showed the ring to Mo Yeon, a ring with silver band and round dark stone, in the middle of the stone she could see an insignia and the line 'Republic of Korea Army' rounded the stone. Mo Yeon took the ring and studied the insignia before glancing at Si Jin's uniform, realizing it was his insignia as a Major.

"That's my class ring. Every soldier has it."

"Ah..." And then, she glanced at the box. "And what is inside the box?"

The Major laughed nervously. "You can open it."

Mo Yeon glanced at Si Jin before giving him back his ring. Slowly, she took the box and opened it, revealing a ring smaller than the previous, but the shape and the silver band were the same. Unlike Si Jin's ring, there was no line of ROK Army and the stone was white, and glowed.

It was beautiful.

"In the army, a soldier who want to ask a woman to marry him must give the miniature of his class ring to his woman."

Mo Yeon raised her head to meet Si Jin's eyes.

"And I want to give this ring to you and ask your hand in marriage."

Thud.

It was really happening.

Yoo Si Jin was indeed proposing to her.

Her early question was repeated again in her mind.

What would she do if Si Jin propose to her?

"Dr. Kang?" The Major asked worriedly.

Mo Yeon was still frozen before she muttered nervously, "Are you...proposing to me?"

Si Jin blinked. "Umm...yes."

"Here?"

"Uh...yes?"

"Is this why you wear your dress uniform? Is this your special occasion?"

Si Jin scratched his head. "Uh...yes."

Mo Yeon's shoulders slumped. "Oh gosh...I'm not expecting this."

Si Jin was torn between nervousness and disappointment for the doctor didn't give him her answer for his marriage proposal. "You're not expecting what? I propose to you or I propose to you in this place?"

"I'm not expecting you propose to me while you wear your formal uniform and I wear my jeans," Mo Yeon grumbled in high voice, causing the people around them finally realized what happened between them. Some female customers even giggled and whispered to their friends or companions.

Si Jin could only smiled at himself and held Mo Yeon's hand. "I don't care what you wear or how you look like. To me, you always look pretty." His eyes stared deeply at Mo Yeon. "I wear this uniform to show you this is who I am, a soldier who is in love with you. I want you to always become my sun."

Mo Yeon's breath hitched.

"There's no one that I want, but you." Si Jin's eyes didn't falter. "Marry me, Dr. Kang Mo Yeon."

Some people were gasped, others were gaped, but Mo Yeon didn't pay attention to any of them. She looked at the ring in the box and her mother's words replayed in her mind.

The time will come when we have to say goodbye to our love ones for eternity. But, at least we can have our time together while we can and cherish it. And the way to spend it is with someone we love, right?

It was the moment Mo Yeon understood every minutes are precious and she didn't want to waste it, and mostly, she didn't want to waste the love from one man she truly loved. She thought she lost him a year ago and now, she wanted Si Jin to become her sun too.

Besides, how could she say no to a soldier who wears his dress uniform for her?

The doctor smiled and looked at the Major's eyes. "Yes."

Si Jin blinked. "You said yes?"

"Umm...yes."

"You agree to marry me?"

Mo Yeon almost rolled her eyes. "I didn't say no, did I?"

The Major finally smiled happily and put the ring on her left ring finger. All the customers, even the waiters, were clapping their hands while some of them gave catcalls. Si Jin's eyes shone brightly and he rose from his chair, extended his hand at Mo Yeon while the doctor eyed him warily. Slowly, she took Si Jin's hand and he pulled her to him. To her surprise, Si Jin leaned down and gave her a deep kiss. Everyone was clapping while congratulated them and Mo Yeon relaxed in her soldier's arms.

Let him showed all the people in the coffee shop that she was his.

And they were engaged.

After some moments, between the noisy voices, Si Jin ended his kiss and slowly leaned away from Mo Yeon's face. The doctor was also feeling very happy and she hugged Si Jin in warm embrace.

"Thank you," she heard him said. "I'll do anything to keep you safe and to make you happy."

Mo Yeon smiled with misty eyes. "I still can't believe I accept your marriage proposal only wearing my jeans. How can I tell this to my friends in Haesung?"

Si Jin chuckled and caressed Mo Yeon's hair, still hugging her.

Yes, she would cherish all the moments.

With him.

I always feel guilty for giving them a beautiful wedding, but skip the part when Si Jin proposes to Mo Yeon. At least, I can do it now :)

Hopefully, you still remember this story and who knows maybe there will be another bonus chapter hehe...
