hoo boy, how did this turn into a discourse pit? now I have to do a bunch of discourse before I comment
@discourse: While Badis's argument sounds good on the surface, I'm troubled by the assumption that a character dating a guy, especially a young character like this, automatically makes them bisexual. It overlooks the pressures of compulsory heterosexuality. While none of my friends have had this experience, I've seen people saying they didn't know they were gay until several straight relationships of theirs had already stalled. Since society assumes everyone is straight, it can take people a while to piece their sexuality together if they aren't. Using this story as an example, Rie may have a boyfriend, but she's daydreaming about kissing her female best friend instead. Paradoxical as it may sound, the fact that she's in a relationship with a boy says very little about her actual sexuality—people don't always date people they're attracted to, after all. There's not enough information to say whether she's bi or straight or whatever.
I say this not so much for Badis's sake. Badis is clearly arguing in bad faith, given how they've imported their pet peeve into an unrelated story and how bluntly they've dismissed the reams of counterexamples people have already provided. But for others who are arguing the same point in good faith, that would be part of my response. (There's also the fact that bisexuality is a wide spectrum, often ranging in practice from one to five on the Kinsey scale, and drawing a hard distinction between being bi or gay/lesbian at Kinsey 5 is quite difficult, but that's probably straying afield of the actual criticism in play).
@story: The page four twist really made this story. It was pretty cute before, but discovering that most of the story is Rie rehearsing confessing to Yuki in her head is weapons-grade adorable. Seeing more of these characters would be delightful. (I also think this five-page comic did a remarkable job fitting a satisfying three-act story arc into a small space in a way a lot of tiny comics don't.)
