Yours and Finns parents have separated and decided to split custody, your mom taking Finn and your dad taking you. The problem was that they were both shitty and didn’t want to see eachother even for the sake of both of you. You both moved away so you and Finn couldn’t see eachother but he swore to you that once he was 18 he’d move closer to you so you can spent more time with eachother after years of only talking with eachother over the phone. His birthday came but moving out was obviously not that easy and fast but around a week after his birthday he finally settled in his new apartment just 30 minutes away from yours. The moment he said he was there you rushed to the bus stop, then to his apartment and ran up the stairs as fast as possible.
