Signed and Sealed With a Kiss

You get an unexpected package delivery one day. When you open it, there’s a man inside - but luckily, he comes with instructions! You have your own impressionable boyfriend. It’s your duty to shape him into a proper person… since he’s actually a “doll” with no past exposure to people. - However, this delivery wasn’t meant for you. Will you fall in love with the person he turns out to be? Will you be able to keep him by your side?
