Siwon's P.O.V

    Today is Yoona's birthday. I don't what to do. "Gah~ I'm really a pabo! I don't even know, what my girlfriend likes!" I sighed. I sat next to Heechul hyung and he evily smiled at me.

    "You! What's your plan?" he asked me.

    "I don't have any." I confessed. Suddenly, SuJu members went to me and they all smiled evily.

    "Geez! When will you going to be so romantic like me!" the evil maknae proudly said. I send him a death glance and he laughed.

    "Yah! We have a plan! We'll help you!" Eunhyuk said and laughed.

Yoona's P.O.V

    Today is my birthday. I hope Siwon oppa can come. But he said he will be with SuJu oppa's for a concert overseas.

    "Yoong! C'mon! Let's hurry!" Taeyeon unnie shouted and I hurriedly went to the van.

    After a few minutes, we reach SMent. building. I tried to call Siwon oppa but he is not answering it. "I hate this day!" I thought to myself. When, we enter SMent. building, I was shocked to see SuJu oppa's. I thought they are on the other country.

    "Happy birthday Yoong!" they greeted me and I vowed at them. I want to asked them, where Siwon oppa is. But I'm too afraid so, I just hurriedly went to our practice room.

    As I entered our practice room, I was shocked again to see a huge banner with my face with something written on it. I read the phrases.
