Damn, My 80-Year-Old Grandfather Is Actually an Alien!

I have a grandfather who is about to turn 80 and has no partner in his life. I have a best friend who is 24 years old, rich and beautiful, and she was just betrayed by a scumbag. She just wants to find a good man who is honest and reliable and doesn't care about his age. So, I joked with my best friend, how about introducing my grandfather to her? Although it is said that the old man is good, the old man is great, and the old man has a minimum living security allowance. I was just trying to make her laugh, but to my surprise... She actually took it seriously! At my grandfather's 80th birthday, my best friend, wearing a white wedding dress and holding roses, actually proposed to my grandfather! "Okay, I treat you as my best friend, and you actually want to be my grandma!" [The introduction is too weak, please read the text! This novel and its characters are purely fictitious.
