Read the LN or WN, dunno which.
Here's my thoughts:
- Real strong start
- Likeable and interesting characters from both sides (except the sister, who is a tad too much of a bitch to really get invested in)
- Dear god I hope they skip a few chapters in a certain arc, that shit was overwhelmingly boring besides a few interactions.
- MC ain't bitch made, he's sorta battle hungry which is something I rarely see in MC's in isekais.
- Doragon is best girl, childhood friend is just not all that interesting compared to her.
