Ikusei Game ni Tensei Shita no ni, Naze ka Kishi-tachi ni Dekiaisaretemasu

On the way home from the game store, I died in a traffic accident - or so I thought, but it seems I've been reincarnated into the world of a training game!? I'm caring for my workaholic personal knight and secretly training with a tsundere righteous thief. As I'm enjoying my training life, he's somehow become more attached to me than I should...but this is a training game, right? (Source: Manga Park, translated)
