One day in SM Entertainment's building, the artists were peacefully eating in the cafeteria while Yoona and Donghae stand in the corridor in front of their training room where nobody else was...

Donghae: So you saw my message...
Yoona: Yes Oppa, what do you want?

Donghae looked into her nice eyes, she blushed…

Donghae: I… I want…
Yoona: What do you want?
Donghae: Everytime I see you, my heart races, everytime you’re near to me I want to hold your hands, everytime you talk to another guy I get so jealous…
Yoona: Oppa…
Donghae: I think I’ve fallen in love with you…

Yoona’s cheeks turned red she was speechless but happy the same time and nervous… Donghae smiled at her, she smiled back and she kissed him gently.

Yoona: Hae… Oppa… I feel the same with you; I want to be with you.
Donghae: Yoong~ I am so happy…
Yoona: Oppa…
Donghae: Let’s go eat something… But please let this be a secret for now…

They walked to the cafeteria without any thoughts that somebody may have seen them, but the CEO, Mr. Kim saw everything through their security cameras…
He couldn’t handle it and called Donghae to his office.

Mr Kim: Good morning Donghae…
Donghae: What is the matter, Kim Youngmin-ssi ?
Mr Kim: Break up with Yoona!
Donghae: … How… did you…
Mr Kim: You stupid, little brat. Have you forgotten that we have cameras in every corridor?
Donghae: Oh.. But Kim Youngmin-ssi, why can’t I be with Yoona?
Mr Kim: You are the face of Super Junior, same as her. When the fans know about this you’ll lose many of them; THINK OF THE MONEY THE COMPANY WILL LOSE!!

Hae walked out of the office, what should he do?
Then he saw Tiffany while walking to his training room.

Tiffany: Hello… Oppa…
Donghae: Fany~~ /hugs
Donghae: My day is bad, I messed everything up!!
Tiffany: Oppa, it’ll be alright!
Donghae: Thank you Fany… maybe, but i don't think so...

At night in SNSD’s Dorm all are in their rooms, Tiffany and Yoona are sharing the same room.

Tiffany: Today I met Donghae Oppa!
Yoona: Really? I also met him. He was really open hearted… /smiles brightly
Tiffany: Oh... you know, to me too… /serious

Yoona was curious…

Tiffany: He told me he did everything wrong today, it was a big mistake he told…
Yoona: hmm… really…
Tiffany: I’m so worried… Do you know what happened? What did he told you?
Yoona: Nothing... nothing unnie… Let’s just… sleep…
Tiffany: Ya~ what happened?

Yoona pretended that she fell asleep, but she cried silently…
It hurt so much.
