Alright, I'm tapping out of this manga. This whole conflict is so contrived, and for the strangest reason: to characterize the MC as an insecure loser? Like, what? The other adventurer tried to poach his magician and she rebuffed his attempt, end of story. Why did the MC feel the need to beg him to not steal his party members when they already expressed their desire to remain as a unit? Then when the adventurer challenged him, why didn't the MC just say no to the duel and strange objectification of Estelle? Like she already said that she didn't want to join the other adventurer's party, why is this even a thing to be gambled? Does her opinion not factor into any of this?
All said, this is coming from someone who reads a lot of low-tier isekai and otome villainess manga so I can deal with generic stories, but ugh, this chapter was mind-bogglingly bad.
