A thing I really appreciate about this manga, which I feel goes a bit unnoticed, is how Takafumi, Fujimiya, and Oji-san bond over their shared passion for isekai stories. Takafumi apparently had a fallout with his previous roommate and didn’t have contact with Fujimiya for a couple of years, and he may also have a strained relationship with his parents since their divorce. Meanwhile, Oji-san is generally a loner and lost all of his isekai friends when he returned to Japan, so it’s pretty nice to see them developing this small friend group.
