The Girl in My House Hasn't Grown Up Yet

Everyone else gets a girlfriend dropped into their lives, but I get a daughter?! And then my daughter and I live happily ever after, shamelessly and without a care in the world? ...Heh. In reality, I'm just a shut-in who got saddled with a three-year-old little girl. Though my daughter's arrival seems to have brought me some romantic luck, I just want to be an ordinary college student, aaagh! (Though secretly, I'm thrilled.)
