Mission: Taekook

Jungkook is 35 years old and Father to Yeona aged 12. After they break the heating in their home they are offered a place to stay over Christmas and New Year by Taehyung and his Daughter, Jia. The girls are best friends and their Fathers have spent too many years being single... can love bloom over the festive period?

This is a story based on the following prompt by an anonymous prompter for the Taekook single parent fest on Twitter:

*While playing with his child, they end up breaking the thermostat of the apartment. As it was snowing outside, they can't live in the apartment without the heaters and it would take 2 weeks for it to get fixed as the workers are on vacation for Christmas and New year.
Jungkook can't go to his friends' house as they are all out of station to see family or spend Christmas somewhere else. His relatives all live in Busan.
When Taehyung heard about this, he offered his place to him and jungkook accepted. Their children will share taehyung's child's bed and Jungkook volunteered to take the couch.
As they spent the days with each other, going out or playing in the snow or having a hot chocolate in front of the fireplace, taekook fell in love.
Now Taehyung doesn't want jungkook to go back to his apartment.
