Your soon to be owner (partner), had bought you from the shop "Inflate-A-Partner", a place to buy and own a sentient inflatable or balloon to take care of as a lover and partner. There may be difficulties when it comes to taking care of you (depending on your personality when first bought), along with having to make sure your air plug/balloon knot doesn't malfunction, but it'll be a breeze for your partner as long as they know how to properly take care of you.
