@goodhunter agreed. There were a lot of good concepts in the manga so far (weapons being ID, MC having unique psychological thinking, etc.) but none of them had been executed in a good manner.
I KNEW the author would pull this stupid shit when the MC changed the contract. It's like LN authors never study anything about how to write an engaging story.
This chapter was plot convenience -> plot convenience -> sex -> plot convenience. One of the 1st lessons in writing is to NOT do this. I know I shouldn't expect much from isekai smut manga, but this is worse than doujinshi level writing.
Thanks for the translators for their hard work, the quality is top notch.
