There's a character type for him, and it's the energy saver (though I'm not sure what it's exactly called and I don't have the strength to find out). "Tanaka-kun wa Itsumo Kedaruge" built a whole series around it. Elsewhere, even in some big titles like "Hyouka", it's the defining characteristic of one of the main characters, though not the theme of the whole story. So, though I won't blame you for interpreting it so, the MC is not extra cold like an ice cube. He just doesn't want to bother with it, feeling like it's too much. In other words, he doesn't have enough energy (motivation) to get involved more than this. In RL some people become like that due to an illness. They can turn even a bit hostile if one tries to push them too much to get involved, as it can be painful for them, physically or mentally.I would classify him as a kuudere since he's basically an ice cube.
Or just watch it normally, cause nobody really gives a fuck.Honestly if really want to go unnoticed to something the caters for a younger age like a movie. Just show up with like a notepad with something to write so it looks like your studying the film for work or something.
You say that until you're in the same exact position as him, mind you these 2 are grown adults and she's acting like a highschool girl with abandonment issues, she 100% made some people in that restaurant uncomfortable with all of her yelling and getting defensive about being looked at as a pervert, when that wasn't even the case with MCYou know, while the guy is kind of based I do feel bad for Noa being so open to him and he just shoots down her excitement so bluntly. Come on man, at least just nod and go "Hmm hmm" to some of those.
I believe thatShes the type of girl that makes you an alcoholic
