Call the Motherland at the Beginning, and the Country Will Give Me a Wife

On the first day after traveling to the magical continent, I dialed "Alien 110". The operator was a girl with a nice voice but a sharp tongue: "First recite your ID number to prove that you are not a fraud." Later, the girl personally traveled through time to save me, but she lost her memory and couldn't remember me. I chased her again and told her our stories every day. She asked: "Why did I like you before?" I said: "Because you are smart." She: "Then I am smart now, so why haven't I fallen in love with you?" Me: "???"
