(Upcoming stories: My Undercover Mission Failed, and Now I'm Carrying His Baby and After Being Reborn, the Scumbag Became My Devoted Fan) The main story is complete. The full story costs only a few dollars, so I hope you'll support it! Blurb: As an ancient sacred blade, Gudao lost the scabbard he loved. Life without his scabbard felt so empty. So he gathered his strength and set out to find him. At last! In a small grove on a campus, he sensed a familiar presence. Bi Geng, clutching a book, sits alone in the grove and shouts with a fist raised: "I can fail! I just can't fail the course!" Gudao: Pfft, so cute. He really is my scabbard. I want us to become one. Bi Geng, who got up late and couldn't find a seat in the library, had no choice but to duck into a small grove... Of course, that's not the point. The point is the man before him, dressed in gorgeous ancient-style clothes. Bi Geng: "Cosplay?" "Classmate, judging by your face..." Bi Geng: "A fortune teller?" "You must be the scabbard I lost many years ago." Bi Geng: "...Are you nuts?" One-sentence summary: The blade knows the scabbard's depths, the scabbard knows the blade's length. They're a perfect fit. Blurb dated April 21, 2019 (revised December 30, 2019), screenshot saved.
