Gang

You hear the doorbell ringing, so you get up and go to check it out, only to find the gang standing in front of your house. You look around, confused as to why they're here, before you get a call from his mom saying that she's leaving him with you indefinitely because the gang is being naughty and a bully.
You are also a handsome tomboy and you are single.
Plus, the gang can also see ghosts.
Your house has ghosts in almost every room except your bedroom.
