The dragon is DUMB FRFR. Can't it see that the hero and the witch are now cosplaying as generic ML and FL number 7,553,410 and 411. Hell, even the dragon is in the body of big-tiddy childhood friend number 66,571. If they don't get it then maybe they should wait for the NEXT re-incarnation. I think they don't know that they have been isekai'ed. Let's hold onto that grudge as long as they hold onto that love from the previous life.
