1. On the other hand, he now gives off psychopath vibes. He smooched her a few times, without any emotion to it, just because it works out for him (piss off Rua), and because she asked him to.
2. Personally, I felt like actual murder-attempt jumps the shark, here. I don't care how rich and powerful her family is, this isn't the shogunate. You don't just stupidly murder someone within a private business, and assume everything will work out.
1+2: The story has gotten too fantastical and silly for me at this point. If previously it was an obvious wish-fulfillment wank fest, but still somewhat grounded in reality -- it now just completely comes across as wacky fantasy BS where anything goes.
Author tried to keep upping the stakes, and it just turned the MC into a sociopath, and Rua into a murderer.
In a few chapters, it might actually turn into a Madeka Box manga, where there are actual superpowers and magic and "tropes".
