Jungkook went home once Taehyung, who was with him at the time, told him to do so. Jungkook walked into the apartment, completely drained and disappointed. He sighed as he entered his room and fell flat on the bed. He had by now started receiving lot of birthday wishes, he had almost an hour before he turned 24.
Jungkook sat up frustrated with how things went with Jimin and wanting to release said frustration looks around the room for his boxing gloves, when he remembers that the night before he had went to the roof balcony to enjoy the view and serenity and had left the gloves there.
He walks up to the roof and was pleasantly surprised to see the whole roof decorated beautifully - there was a table for two, flowers and candles and a cake with the words I love you. Jungkook knew it had to be Jimin, because he saw a plushie of cooky and chimmy on a mattress at the corner of the roof which was also beautifully decorated with sheets over it like a tent with colorful lights over it. On the side of the mattress was a bottle of champagne and two glasses.
Jungkook's eyes tear up in joy - he didn't forget. He remembered and he loves me back.
Jungkook couldn't control his excitement as he calls Jimin.
