Red-haired alien BL

I can't remember if I saved it and I am too lazy to look for it, but do you know the name of the BL with the rea-haired alien guy and his little blob friend? And the love interest is this brown-haired human guy, and the alien dude basically moves into his house? And his parents (the alien dude) are also made up of a redhead and a brunette, and the second couple is a blonde and something else?
