First rug-sweeping and now the author is trying to pull some post-hoc rationalization/reasoning bullshit for Giselle's attempted lynching of Cross? Somebody correct me if I'm wrong, but I do not recall it ever being established that the setting is in such a crap sack kind of world that adventures need to go out of their way to crush the weak to get ahead and/or survive. I mean, leaving Cross alone after fucking with him a few times was an option, yeah? Just let him find out firsthand that no one is going to want to pair-up with and carry his (presumably) worthless ass through dangerous battles with monsters and disputes with shitty nobles. To me, this whole situation just reads as The Orphans reaping what they have sown and pulling the MC into their mess.
I might have been onboard if Giselle and her crew finally owned-up to and apologized for what they did, before then asking Cross to help them in exchange for then helping him achieve his dream of becoming a great adventurer. But no, blame the MC instead for the consequences of your actions. Such character development, much likability
It makes me wish the author would have instead gone the route of MC becoming an OP solo adventurer with just his harem Mommies by his side... and eventually recruiting the hero girl along the way. Because with this setting, all I can muster is: "Let them fight" and "You get what you deserve" for Giselle and company.
