It’s a cheap way to show character depth/developement. Whether you want to admit it or not BL contains some of the most poorly written stories in the whole of animanga. Full of very cheap characters with no depth and a boring/mediocre story. Yet those very manga are usually really popular bc if it has a nice art style ppl ignore those things. What the author of this manga did in chapter one is to show one thing only and that is krieg’s character development and to make him more than one dimensional. You take it away and you’re left with “an adventurer that hates doctors”. I feel like the author could’ve achieved the same thing by just having him be an asshole without the rape. One thing she underestimated is that even if the uke doesn’t consider it rape The seme still intended to rape and assault him....so he’s still a rapist.

Actually if there isn't any rape/harm and if story only had angst/argue in the beginning, this manga could have been nice with good relationship development. But mangaka ruined this chance I guess.
