You're addicted to copium if you really think the author isn't still writing weird subplot between the two. The author is a creepy dude who got lucky with catching the attention of people that like fluffy cute things and has been working on hentai revolving around the two girls while they were in school together. The entire premise of this romance was "big man on tiny woman" which can be done in a non-creepy way, but the author also regularly wrote that the character herself is also very childish in how she behaves and he still pairs her up with a giant dude who acts more like a father than a love interest because? They don't have similar interests, they barely talk outside of regular interactions between coworkers, and honestly its super tone-deaf to write a story about a borderline 4 foot tall woman not having any feelings of being unsafe around a 7 foot linebacker of a boss towering over her regularly making fun of her hobbies for being childish. Looking back on the story, this really comes off as someone who hasn't worked in an office setting before but finds the concept romantic and wanted to fetishize it with the character designs. Igarashi is just a textbook example of someone trying to explain the concept "all women want to marry their fathers". The FMCs friend is the most clear cut fetish character I've ever seen, reading off her physical characteristics is like reading the tags on a hentai website. If you honestly think that the author would write a character in who is tall, brown skinned, pointy teethed, was on the swim team, had a rebellious "cool girl" phase, AND they secretly had same sex feelings for their friend for reasons other than to fetishize I wish I could see the world like you do
Dude,
I know. I was trying to word my opinions more politely than "I don't think the author will visually depict Yuuto and Natsumi getting together because he's a coomer weirdo who hates drawing his porn OCs with men unless they're faceless or off screen".
I'm honestly glad you're on the level because I've been sperging out for ages on the individual chapter releases where copium huffers keep saying "it would be less creepy if Natsumi wasn't actually in love with Yuuto at all but only with Igarashi". Like bro, she was first attracted to Igarashi in middle school and Igarashi's body never changed from then. Also somehow they DON'T notice that Yuuto and Igarashi are drawn with the same base model. If you take away their hair and clothes they're the same characters with the same proportions and the author did it on purpose. Natsumi is a weirdo no matter what.
The thing with Natsumi, I think, is the readers who only read this manga on-and-off (and aren't aware of Shiromanta's fanbox) don't see the full picture and fill in her story arc with assumptions because their brain gets turned off when they see a big titty tan tomboy. "Woah she's so tragic and sad and kinda gay what an adult storyline" like no, she's an immature, clingy, and dishonest woman who's attracted to lolis and shotas. She exploits Igarashi's obliviousness of her feelings to satisfy her personal needs and consciously teases Yuuto despite feeling like she's leading him astray.
Surprisingly too, Yuuto is the one who acts most like an adult in the story, especially since it's shown in chapter 220 he outright says he's aware of Natsumi's feelings for Igarashi but still fully loves and supports her regardless. I assume it's to show contrast between how Natsumi and Yuuto's outward appearances are the complete opposite of their emotional maturity, but it's not wholesome in any way.
It's infuriating how a lot of people were tricked by the anime into thinking this is a cute slice of life where the onee-shota is literally the only weird thing about it when the whole story is an excuse plot for Shiromanta to get paid for drawing his porn OCs.
And I agree, this comic is about a big bara man being paired up with a midget who's drawn like a child. If you couldn't sniff out the author's degeneracy from day one you're either dumb or blind.
Also yes, I'm aware he's drawing a kink doujin in his fanbox where Natsumi does kinky stuff with Futaba while they were still in high school. There's a giantess scene in there so I'm assuming it's either a dream sequence or Natsumi's fantasies. Either way people need to open their eyes and start actually seeing this manga for what it is.
