~Feelings returned and unreturned~

y/n won a competition. The prize was to live with 5sos for half a year.
y/n and Calum has met sometimes before and they got along very well- they are bestfriends. Calum gets a big suprise when he and the guys are picking her up on the airport, Cause he didn't know that y/n was there. Things go both ways for everyone in the 5sos house!
