"One, two, three.. NOW!!!" 

"IIIIYYAAAA!!!!!!!!" 

"One, two, three.. NOW!!!" 

It's 5 years ago, Pauline had one year in the agency, she was 16 years old. She knew Key in the school, she fell in love of him, and in this time, the two entered in the company. Key was her best friend, until them became into a couple. They always were together, they love each other so much; when they were trainee, they enjoy their summers in his houses but they missed each other..  After a little years, they were qualified for their first mission. Recover the most important object from the National Museum of Korea. That object had a lot of years and it value was $100,000,000,000,000.000 of dolars (Hahah to much??). They finished the mission with success, and their fame rose until the sky, all the city knew their names and all their missions are finished in a great state. After 8 years, they married each other.

They were happy, all their lifes together.. their last mission ocurred before Pauline went with her father, the same day that Taeyeon confessed to Tiffany...

"Pauline, Key, please be careful, all the nation trust in you two.." 

"Yes Sir. Don't worry, we can do it" Pauline said

"Excelent. So.. Let's go" The couple went to their car, they were ready. "Key.. please take care of her ok???" 

"Don't worry Sir. I'll do" Key closed the door and started to drive. Pauline sighed "EH?? What's the matter Pauline???" 

"Nothing Key.. only.. mm Today is Taeyeon's festival and I can't go.. because MilkyBoy decide attack us again..." Pauline explained

"Mmm baby.. if you want, you can go with your brother and.. I can finish the mission" Key suggested

"Nothing of that love, all the world know.. you and me.. will be together forever.." Pauline smiled to Key.

30 Min. AFTER.

"KEY RUN!!!!" Pauline yelled, Key was in the floor, he fell because we stepped on a trap. 

"I'm behind of you!! Run Pauline!!!" Key gave to Pauline the CD, she started to run to their car, the soldiers of MilkyBoy went to Key, he could stand up before them arrived, he put out him gun and shot to everyone, when he finished with them he ran to Pauline's direction, he went out of the building and he saw his wife between MilkyBoy's hands 

"One more step and your wife's head will make KABOOM!!!" MilkyBoy said

"... " Key thought. He was looking around trying to find something for help him..

"Put your gun in the ground!!!! MilkyBoy yelled, Key obeyed his order.. "Fine.. now.. stay away of it!!!" Key did 3 steps behind his gun "You two guys are very stupid.. Really.. Did you think that you can stop me??? come on.. I'm the best villian of the country!!! the best criminal of the world!!!" 

Key was in his place, he could saw a tube in the floor. "Hey MilkyBoy.. you have something in your clothes.." Key said

"Eh?? what are you saying?? what is this???" MilkyBoy looked at his jacket.

"Yes.. you have some.. OF BLOOD!!! PAULINE.. GO DOWN!!!" Key use the tube for hit MilkyBoy's face, his nose and mouth was bleeding, his jaw and nose was broke, Key ran to Pauline. She launched herself to the ground for dodge the tube. "Are you ok?"

"Yeah.. I'm fine thanks.." Pauline smiled

"Well.. do you have it???" Key asked

"Yeah.. here.." Pauline showed to Key a CD. "This is the program from the principal hospital.. about the mutations on humans and how we can make an hybrid with animals and.. humans" 

"Uh.. in a bad hands.. this is very danger for all the world.. Don't you think??" Key smiled, he took the CD and put into his jacket

"Yeah..well.. let's go Key.. we need to finish our mission" Pauline said, she took Key's arm

"Whatever you want Pau" Key kissed Pauline's cheek. They called to the police, and MilkyBoy was capture. Pauline recived a call of her dad, he needs her in Korea. The next day, Pauline flew to her origin's country. Key was alone in Spain, he missed Pauline so much but one night, he recived a call from Mr. Kim, he was asking for help because Pauline and Tiffany was kidnapped. Key didn't think that two times and he went to Korea.

"Don't see me like this, you're scared me.." Key said to Taeyeon

"Sorry.. It's only.. mm Why you're here?? Who called you?? and why you know my sister???" Taeyeon said

"I told you.. I'm here because I need rescue Pauline and your girlfriend, and your dad called me and you'll never believe in me if I tell you who I am and what's my relation with your sister" Key explained, he drank his tea

"Aiisshh.. she's my sister!! I'LL PROTECT HER NO MATTER WHAT!!! Who are you and why you know her??? Are you another agent???" Taeyeon asked, he was a little curious.

"Really???!!!" Taeyeon was surprised

"Yeah.. Come here.. I'm.." Hey stopped

"Ahh.. you're only her partner.. hehe that's great.. hehee" Taeyeon laughed 

"Yep.. that's all.. I'm her partner.." Key smiled, Taeyeon drank his tea, in this moment..."And I'm her husband" Taeyeon spat all his tea in the table, he started cough without control, Key only drank his tea. In that moment Taemin appeared in the room

"I'm here Taeyeon" Key said, he was behind Taeyeon, and he only saw how Taeyeon yelled because he didn't see  him and he fell to the garden, in the flowers of Mr. Kim "Sorry Taeyeon.. But if I were you.. I'll repair the flowers before Mr. Kim see them.." Key smiled and he went into the house again

"When he.. how he can... where he was????" Taeyeon said very afraid, as he caught his breath again

"Ah.. I almost forgot Taeyeon... your dad is looking for you!!" Key said to Taeyeon, he looked him only a seconds, after that, he took out his phone and took a picture of Taeyeon "You'll look so handsome.. I want this look that you have..."

"All is ready boss.." Donghae entered in the room

"Fine.. well ladies it's simple.. I need your voices.. we'll find Taeyeon.. and you'll help us.." Eunhyuk explained, Tiffany became nervous and Pauline only took her hand.

"I'm not going to do that.." Pauline said

Eunhyuk frowned "Of course you'll do it... because if you don't help me.. Tiffany's mom will say goodbye to her life" Eunhyuk yelled, after that Tiffany started to cry in silence, Pauline didn't have any choice.. She was worried for Tiffany's reaction.

"..." Pauline thought.

"Fine.. here.. take your cellphones and dialed Taeyeon's number, talk with him and tell that you'll meet him in one place.. whatever you want.." Eunhyuk gave the instructions. The girls obeyed, Pauline called him first.

"Yeah.. try it Tiffany.." Pauline told to her sister in law.. Tiffany was very nervous, for first time in her life, he wished that Taeyeon don't answer her call.
