The only thing, literally the only thing that could ruin this series if it becomes a harem of some sort. One pinning after Lecan? That's fine. Hopefully if such a thing happens, she has some agency outside of that (I have no expectations though). I like Lecan's stoicism within the confines of his professionalism, not in social settings where we have to deal with that dense protag shit.
Thank you for coming to my Ted Talk.
