BUT kume gives me HELLA regression vibes (for all you non-psych peeps or people who just don't know, regression is the returning to a less developed state, usually to a child age. it happens a lot to people who have experienced trauma/poor upbringing in their life.) idk when he first crawled into bed with nogami, it just felt like/seems similar to when a child would crawl into bed with their mother or father for comfort. his "pushiness" also gives me a child-like vibe; it doesn't seem malicious or calculated but rather like he's too simple-minded and misinterpreting things/taking them too literal, like a child would. also that scene where he is speaking with nogami about his wife and his ex, nogami even points it out "he's withdrawing into himself." now this isn't an explicit sign of regression, it could def be something else (many people who suffer from anxiety and other mental illness to do it as well) but many people who experience regression do that pose, to try and seem "smaller."
anyway, the "sex" scene seemed very strange to me. like his thought process was "i am lonely. nogami is lonely. sex feels good and makes me feel less lonely. so that means it should also make nogami feel good and less lonely. so i should have sex with nogami." very simple, right ? perhaps we'll learn more about kume to understand why sex was his first thought to combat loneliness. (sometimes victims of abuse/mistreatment/neglect will turn to this; or maybe it has something to do with his ex and how he had preferred women. it probably made kume feel inferior. <edit: kume had said "the usual" it was established that his ex was a scummy cheater but i suppose it also carried over to sex. he most likely did not care for kume at all during sex and only took instead of also giving back.> all in all, it's obvious kume has skewed view on what sex is and should be.) or maybe i'm reading too much into it and it was just a drunk kid wanting to fuck and/or pay back nogami for being kind and sex is the only way he knows how to)
so kume has def been a victim of neglect, yeah ? by his parents and his ex. i think that scene with taki (nogamis friend) is what really set him off. when taki called kume a "chance," that made kume feel like he was actually useful and was actually being noticed for once. perhaps even needed.
i don't think kume is manipulative (or at least not knowingly manipulative). i think he has a very child-like mind and because of this misinterprets things, resulting in the sex and the cancellation of the property. maybe i'm just reading too much into it a simple plot and character ╮( ̄▽ ̄)╭ it's prob gonna have like 5-6 chap and most 5-6 chap bls don't really have subtleties or deeper meanings :/ (or maybe the author is just trying to subvert our expectations and kume is actually a psychopath or some shit and he's obsessed with nogami ! idkk)
