I picked up Tensei Kizoku no Isekai Boukenroku (Japanese subtitle: Tensei Kizoku no Isekai Boukenroku) hoping for something along the lines of Lv2 kara Cheat without the problematic romance aspects, only to instead get something closer to Isekai wa Smartphone to Tomo ni. A significantly less believable Smartphone. Although I tried to force my way through the childhood arc to see if it maybe got better… the rescue of the princess was one questionable romance flag too many.
Teisou Gyakuten Sekai no Doutei Henkyou Ryoushu Kishi also has believability issues, albeit less severe and centered on the setting itself rather than the initial event development; the role reversal is poorly implemented and surface-level at best (Honor of Duty looks like an intricately woven masterpiece in comparison). Worse, far worse, is that the protagonist appears to be an insufferable incel who can’t stop talking about his dick.
