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?
