>FLASHBACK<

"Hey, Mimi?" The nine years old boy spoke.

"What, Jongin?" She asked as she turned to face him.

"Lets make a promise." Jongin grinned while holding Chanmi's hand.

"What promise?"

"Lets get married in the future. And promise me, you'll love me forever." He grinned childishly making the said girl's cheeks flushed in a beet shade of red.

"Promise. I'll love you forever." Chanmi replied sheepishly.

"Jongin! You still need my permission to marry my baby twin!" Chanyeol said with a frown. 

"Channie, I'm not your baby twin. You are my baby twin. You're younger than me by 5 minutes, okay?" Chanmi said, rolling her eyes in advance but smiled nevertheless.

"But still! You're smaller than me so you're my baby twin." Chanyeol said with a pout on his face.

"Mimi? Don't leave me, okay? Promise me?" Jongin said while sticking out of his pinky finger. Chanmi chuckled happily and soon joined his pinky finger with hers.

"I promise, Jongin." Chanmi smiled.

Jongin suddenly leaned in and pecked her lips making both of the twins' eyes widened in shock.

"J-jongin..." Chanmi stuttered, touching her lips using the tip of her index finger.

"HEY THAT WAS MY BABY TWIN'S FIRST KISS YOU IDIOT" Chanyeol shouted while taking out his handkerchief.

"Here, Mimi. Wipe it off." Chanyeol said seriously while handing his handkerchief towards his twin. 

"Don't wipe it off, Mimi! We're going to get married in the future, right?" Jongin asked while holding her hands.

"Mimi, I'll tell mom and dad that you let Jongin kissed you." Chanyeol threatened his twin playfully.

"Shut up, mama boy!" Jongin said as he stuck out his tongue towards his best friend.

"Mimi, promise me, even when you're married, I will always be your number one, okay?" Chanyeol said with pleading eyes making her chuckled before giving a peck on her twin's cheek.

"Of course! You're my favorite dorky twin!" Chanmi grinned as she saw her twin's frowned.

Chanyeol, Chanmi and Jongin had been best friend since the was 7. Chanyeol and Chanmi are twins. They looked alike but Chanmi look beautiful for her age and Chanyeol was a possessive brother. There was once when Chanyeol fought with a boy who pushed Chanmi, making her cry. 

And that was the day when Chanmi, lost her first kiss to the boy, whom she thought will be her white knight, forever.
