"Annyeong, Bangtan!" Amber Liu bursted open the door, surprising the 7 members of the hugely popular boy group. Jumping up in shock, Jimin and J-Hope groaned as they noticed it was only their noona. 

"Noona~Why did you do that? You know us two have soft hearts," Jimin pouted as he latched onto J-Hope's arms, looking around carefully to make sure that no one else was going to pop out and scare him like last time. 

Laughing brightly, the female rapper simply hooked her arm through the group's oldest member before smiling cheekily, "I'm just gonna borrow Jin ah for a few..." she pretended to think, "hours." 

"Wait, noona! You can't do that to us, he's the only one who can cook something edible!" V panicked, his eyes widening as he turned to look at his fellow members for support. However, the rest simply blinked before diverting their gazes away. They had learned early on not to annoy the tomboy too much...it was bound to be disastrous if the usually bubbly girl turned angry, and this situation has arised at one point when V was not there. Which explained his obliviousness. 

"B-But...I'm hungry..." Amber squeezed tightly onto the '92 liner's arm, looking up at him with doe almond eyes and the oldest man immediately turned into puddle. And here he thought he was supposed to be younger than her. 

"Jungkookie can cook too, Taehyung ah. If not, I'm sure manager hyung wouldn't mind taking you out for some meat," Let's go, Amber." The man hurriedly usher the girl out of the room before trouble could arise, and the tomboy turned around to stuck her tongue out at V. There was an ongoing competition between them after all.

"Amber ah, where are you taking me?" Jin questioned, shivering against the rigid winter wind as he huddled up against his girlfriend. She was unusually warm and aegyo-ish today, he realized, but he really didn't mind it much as it was normally her who comply to his every wishes. Being the 'umma' of BTS was tough, and when he found someone who took care of him so kind-heartedly, he had fell completely for her. And she just so happened to be the SMTown's resident tomboy. 

"Home! It's cold and I'm hungry and I want to watch a movie!" The female smiled, grinning up at him. Chuckling, Jin couldn't help but to lean down and placed a gentle peck on her lips. 

"...!" The realization came a few seconds later for Amber when she suddenly realized that her source of warmth was nowhere near her anymore. Yelling after the BTs member, the tomboy gave chase to her boyfriend before they ended up arriving at her apartment earlier than usual. "Don't open the door...!" She shouted as Jin took out the key to her place and inserted into the hole. Her warning came too late, however, before the door bursted open and pink sparklers flew all over him. 

"Happy birthday to you~" Jungkook started to sing but couldn't help and started laughing when he saw his hyung's face. The other 5 BTS members peeked around their maknae and chaos soon reigned when their 'omma' realized what just happened. 

"Amber! How could you let these...scoundrels into your place?!" Jin whined, latching himself onto her arm and hiding behind her in case anything else happened. 

"I told you not to open the...Surprise!" Amber suddenly screamed and moved out of the way as a flying cake wheezed past her, landing perfectly on the younger man's face. 

"Happy birthday, hyung! We're gonna leave now, noona. We're too young to die!" The remaining BTS members scrambled for their lives, squeezing past the stock-still couple before sliding into their car as swiftly as possible. There was no way they would give their hyung time to get them all punish...

"Jin. Jin ah. Ya, Kim Seok Jin!" Amber shook him out of his trance, waving her hand worriedly in front of him. "What happened? You suddenly didn't move at all, and I was getting worry..." 

"But...Jungkookie and...Namjoon..." 

"What? What are you talking about? Your members aren't here. We left them at the studio, remember?" 

"Wae? But I swear...!" The BTS member finally regained his senses and looked around him. True enough, they were at Amber's apartment, but traces of the previous cake accident were nowhere to be found. Staring at his girlfriend in confusion, his brows furrowed slightly before he sighed. "It was all a dream...Thanks god..." 

Slumping against the warm body beside him, Jin wrapped his arms around the smaller girl and brought her into his laps. Placing his head on top of her, he tightened his embrace and smiled, "You're all mine, Amber ah..." he whispered, his voice sounding dreamy and much sweeter than usual.

Chuckling, Amber couldn't help but to let her eyes wander to the trash bag at the corner of her apartment, filled with the fallen icing from his birthday cake. He really was so adorably clueless. "I'm not going anywhere, don't worry."

"...Can we watch a Disney movie?" He shyly asked, sliding his head down to landed on the crook of her shoulders. Tilting her head as though to consider the suggestion, a pout from him was all it took for her to reached for the Disney collection on the shelf. He was to blame for there to be anything remotely princess-related in her apartment...and oh yeah, pink. 

"Which one?" She asked, trying to reach for the remote. In her quest for the said object, the female rapper did not notice the slight frown that overtook her boyfriend's face, and before she could even think of getting anything, a strong force propelled her backward against Jin and the tomboy merely laughed at her boyfriend's antics. 

"Ya, Jin ah, I already told you I'm not going anywhere. Didn't I already said you belong to me so many times? Even if you want to leave me, you won't be able to," she reassured her, trying to sit back up so that she could start the movie.

"But what if you change your mind? And find someone else? What if you find someone cuter than me to take care of and you decided you don't need me anymore?" He asked, his arms slowly tightening around her as his expression turned darker and darker by the minute. 

"Jinja, you're already 23 and you're still so childish," Amber affectionately smiled before she leaned in and kissed him fully on the lips. "Happy now?" 

Grinning brightly, Jin nodded before rooting her upright again. However, his arms never left her waist and instead, they had move to bind her to him even more. And when she questioned him as to how they were ever going to start the movie, he simply plucked the disc out of her reach, pushed it in the DVD player, and pressed play. All done just so she won't be able to get away from him. 

"You know what, I give up. Happy birthday, Jin." Amber congratulated him, snuggling against the broad chest she had grown to love. Who would have known that all it took for him to man up and confess...for it to even lead to that in the first place...was her being the first one to console him when he lost the game on A Song For You. Love really does works in mysterious ways. 

This is as fluffy as it can get. Jin might be a bit out-of-character here but this is just how I imagine he would be like if he ever get an older girlfriend ^~^ And as you can all probably guess, this was inspire by f(x)'s new song, "All Mine." I am in absolute love with it and when I first read the lyrics' translation, this story popped into my head. A slight fluff with cameos by the other BTS members!
