A lot of balloons were decorated all over the university with a permission by the owner of the school, everyone was amazed by the power of the Choi. 

  "Turn left, oh push it up a little more. Yeah-!"  Yoona commanded to minho who is trying to put Krystal's poster on a tall tree.  He jumps back to the ground and looks at what he did. A smile appeared.  "She looks gorgeous here."    Yoona nods in approval. There're only 10 people here including Siwon and Sica. The sister lied to krystal that she had a meeting around 3am so she couldn't stay home until morning.  Everyone looks so busy, trying to make a flying balloons and ropes it on the gate and trees.    "Sica, we should make it quick. It's 6:30am and there're plenty of works that we should finish by now."  Siwon exclaimed as he's looking at his wrist watch. Minho came to his brother.  "How is it hyung?"  He asked, Siwon is roping the balloons with a help from jessica.    "We can't finish it by 8 minho-ah, I haven't call a restaurant for food and drink yet."  Sica said frustratedly.  Minho frowned while crossing his arms, he then saw a group of students, they're his junior anyway, though he didn't talk with them before but he's sure they're nice.  "Prepare for the food and drink, the others stuff, let me do it."    Minho said silently, then he quickly approaches them. "Excuse-me, could you help me please?"  His juniors look at him weirdly, this is the first time in their life that the famous sunbae at school talks to them.   "I need more people to finish this since today is my girlfriend's birthday, and i keen to surprise her."  There're ten people here, they look at each other for a while before nodding their head.    "We're going to help you sunbae-nim."    Minho smiled thankfully while bowing his head many times.  "Don't be too formal with us, sunbae. We're a huge fan of you and Krystal sunbae, anyway."  Another student from the group said, minho grins appeared.    "I can't be any thankful than now."  And then they all start putting their bags away and go to Siwon, finding if there's anything they could help.  Meanwhile, Other students who just came to school offered to help them as well.    "Nana, what do you think about this?"  Amber, one of Krystal's close friend asked. Nana who is busy drawing some cartoon quickly takes a look at her friend.  "I have no idea, ask Luna."  She said, and continues with her work.    "Luna, how's my drawing?"  Amber asked, Luna looked at Amber as she lifts her thumb up.  "I'm sure kryssie must like this, look at minho! He's working hard for this."  She said. They three was invited by minho as well, who could forget them since they're Krystal's closest friends here.    "Hey girls, how are you doing?"  Minho approached them. The three girls grin.  "Everything is good, I can't believe that many people actually offering to help us."  Luna answered, minho lets out a soft chuckled before he wipes his sweat.  "I'm really thankful to them."    "Because they know that they'll get free food and drink later on."  Yoona who appeared from nowhere added jokingly causing everyone to laugh.    They all working together for another hour.  "Anyway, is anyone seeing suzy?"  Yoona suddenly asked since she couldn't saw her friend. "No"    Some people answered then they continue their work again.  "I saw her a while ago, she looks so rush."  A random girl said, yoona frowns.  "Maybe she's sick, she looks somehow pale."  And then no one is talking about suzy anymore.      It's 7:45am in the morning, surely krystal is on her way to the university now. She can't help but feeling upset, her sister wasn't here to celebrate her birthday, her boyfriend is in Japan now, even her best friends forget about her birthday and didn't even text her like what they always did before.    She sighs silently as she keeps driving to her school, the gate was closed and it makes her frown appeared. Generally the gate would be opened by this time.  "It's my birthday, I hope everything will be perfect. No bad luck to ruin my mood again, please."   She pray then stopped her car near by the university. She takes her bag and jumps out of her car, suddenly her phone rang, she takes it out and saw sica's number.      "Hey Kryssie."  Jessica spoke through the phone, everything is already done. Minho now trying to fix his hair with a help from Yoona and other students, they all just can't wait to see Krystal's reaction. Everyone who used to hate minho and krystal being together before, now end up shipping them both, they're so touch to see minho who putting all his effort, trying to make his girlfriend happy and they can't help to feel envy as well.    Minho is with his uniform without a tie, his left hand is grabbing the purple and white flying balloons while his other hand carrying the cake carefully.  "you all have to standing in two queues, and when Krystal walks inside, we have to open the way for her, minho will standing there with those balloons and cake, when she's in front of minho, we will sing together, okay?"    Yoona said quietly. Many students with flying balloons and a small picture of krystal and minho together, already standing in two lines, waiting for krystal to come. Minho can feel his heart is racing as he keeps listen to sica who still talking with krystal.    "Where are you now?"  Sica asked.  "In front of my school, unnie. Why?"  Krystal said. Jessica lifts her thumb up to show everyone.  "Aw, I just wanna check on you, baby. Alright. Study well, Unnie loves you."  Jessica said, then she hung up.    "Everyone, krystal is going to step inside this school soon, beware!!"  Jessica exclaimed, a lot of students nodding their head with a smile, they know that it's going to be fun.    "Luna , Amber, it's your job now."  Nana said, they both nod.  Luna and Amber have to walk outside and cover Krystal's eyes with a black cloth, so it'll be more surprise for her.    Luna and Amber quickly running to the gate, they also feel
