[Western Crossover] My Pen Pal Came to Find Me

Asa had been dead for a year and back to life for two, yet his pen pal still hadn't written back to explain himself. After completing the local mage's trial, Asa resolutely left town and traveled to the world where his pen pal lived. What he wanted was simple. First, find his pen pal. Second, ask him to his face what had stopped him from writing back. Then he discovered that his pen pal wasn't home, and the location marker was in an unknown region. That was fine. He could just look for him at the mailing address they'd used to correspond. One day, a mysterious guest suddenly arrived at Wayne Manor, claiming to be the pen pal of the late second son of the Wayne family. Asa: "Grandpa Jason, hello. Dad Jason, hello." Dad Jason, Batman: "..." Grandpa Jason, the butler: "Hello." Important: 1. The male lead is from a game world. He's an adult, and he and Jason are pen pals across worlds. 2. He knows the basics, but lacks practical experience. 3. OOC!!!! Jason is the pairing. Theme: Live earnestly
