Uchu Kyu Hatsukoi [2] (Kadokawa Tsubasa Bunko)

[Machine Translation] My name is Tsubasa Konno. I live with my father, elder brother and younger brother. The perfect Luka-kun and his family moved into the house next door (from outer space!), and my life changed drastically! ), my everyday life changed drastically! But if Luka-kun's "trial life" on Earth doesn't work out, he will be sent back to his spaceship. A long-distance one-sided love affair on Earth and in space is just too much! The only way to stop me from leaving him is to protect his secret and make everyone on the planet Rana love me and Earth...? The strongest and invincible neighborhood love with a space-class handsome guy.
