I Can't Stand Being Reborn as a Mecha.

The social beast only knows how to work, but does not know that the boss is a robot; the earth is the only home of life known to mankind, but mankind does not know that it will be colonized by Krypton. Until the day when the alien beasts invaded, I was still fighting with the evil robot boss. Don't ask me who I am, I'm just a quiet handsome man, even if I'm reborn as a mecha, I'm still a handsome man!
