Jimin got Taehyung and the rest of BTS to make Jungkook busy with recordings or dance practice or the like while he baked a cake and cooked a birthday meal just for the two of them.
Jimin cleaned the house, cooked the meal and decorated their private rooftop for a perfect romantic date when he slipped on Yeontan's toy on top of the stairs and fell down the stairs spraining his ankle. He was rushed to the emergency once he managed to call Taehyung in secret.
