To be fair, the MC is a bit of wacko for just knocking out someone for saying they were pitiful, when they were in an objectively pitiful situation, that they knew was pitiful.
Hard to feel bad for them.
And I don't see the potential here, just feels like generic fetish art with a rushed story.
If being a lesbian is "objectively pitiful" in your opinion, why are you even on this site?
Way to jump to conclusions.
While Mr. White Knight's choice of words, describing her as pitiful, was very poor (insert Joker from The Dark Knight meme here), he wasn't necessarily referring to her being a lesbian, but probably to her being ostracized and bullied – in other words: her suffering.
Whether he was doing it to actually intervene in the bullying (there are usually rather high-status defenders in a bullying dynamic that can and will take measures to somewhat shield the victim) or just wanted to pad his own ego remains unknown. It's hard to tell from that little snapshot, the exposition happened rather quickly, from what I remember it usually takes a bit longer for a bullying dynamic to establish and solidify. It works as a narrative setup, but could have been handled better. Having it spread out over more than a day or even told via flashback (as suggested previously) might have worked better.
Her reaction wasn't technically appropriate, but completely makes sense in context. I mean, the one time I started a smackdown in school was also just a misunderstanding during which I split the other guy's lip and he knocked me out. Not my proudest moment, and I'm pretty sure she'll eventually think the same way about it, even if it "made sense" in the situation.
Yikes, once again I am reminded of how blessed I was in some regards. I'm pretty sure my parents would not have minded me being gay, seeing as mom's a lecturer on gender studies and all... For a time I thought I was gay when I was fooling around with a bestie of mine (bi-curious would probably describe it best) and even told one of my classmates, who, probably fortunately, didn't tell anyone else. Even so, probably wouldn't have changed all that much, I was already the designated bullying victim at the time ;)
Looking back, it's kinda striking that there was no a single openly gay student at my school, though actually, most students' sexuality was more assumed than known – how could you really tell with single people? I think two of my friends were, but they never came out and I lost track of them since, and one pretty popular teacher was also known to be gay.
LGBT issues were a very minor part of sex ed in 2000s Germany. They were mentioned, but I don't think they played a major role in the curriculum.
And what's with that obscene hourly wage? That's more than I normally make (before tax) in a month, nearly twice what my wife makes in a month. I get it, working efficiently and being lazy as a freelancer can increase your hourly wage, but 530k Yen per hour? That's soccer player amounts of pay.
