So far, I haven't seen anything really fetish-y in it at all, especially not by the typical yaoi standard (in the manga at least, which only has 3 volumes out so far; haven't seen the anime so can't confirm there). It's got some genuinely sweet moments and actual character/relationship building in it, instead of just the bean-flicking material seen in most yaoi shit. The artwork is really nice, the attention to detail on the instruments is pretty cool too for an fellow music nuts, and story's solid for what it is. Each member of the main four ensemble have their own distinct personalities, their own issues and insecurities, hobbies, and jobs away from each other. But perhaps most importantly, I never got the impression that a character was conceived with the writer's only thought being "This is my new gay OC!". Instead, it appears that the author here actually thought of these crazy, newfangled things like 'personality' and 'individuality' to create their characters. Surprise to no one, it actually works!
Anyway, the main endgame couple, Ritsuka and Mafuyu, don't even start out really caring much about each other. Matter of fact, it takes a little bit for them to go from basic acquaintances to 'Eh, he's okay', and then once they're more friendly, they stay like that for a good while to build on other things. Ritsuka is a 'no books, only music' type of guy that cares almost too much about people in his life, but then gets frustrated by how much he cares. He can be snarky and a bit stubborn, but never really crosses into immature level, which is so welcomed to me. Then, there's Mafuyu, who almost seems like he has an actual touch of the 'tism. He has such a hard time developing meaningful bonds with other people, doesn't talk much because he doesn't know how to express himself and thus just decides to be silent, he will straight up just run away from a situation if he doesn't know how to respond to it, he's very bluntly honest to everyone with no sense of how others will take it, and has a hard time not taking jokes as literal comments. The two bond together over something as simple as a guitar at first, and from there, everything feels like it develops at a very natural pace. No one's big, dark secret is leaked within the first couple of pages, no real pandering, no weird fetish shit. Just two older teens drawn to music for different reasons and getting closer because of it. Sure, one has more emotional baggage than the other, but that's also handled pretty well, imo.
Even the secondary couple, Haruki and Akihiko, don't fall victim to anything I'd consider bad writing, both having their own complete characterization and relationship focus outside of Ritsuka and Mafuyu's. Akihiko is known to be a womanizer (because bad boy with piercings), well-known to be hot-headed, passionate, competitive, and he comes off far more confident than he really is in both his skills and his life in general. As a matter of fact, it's this deeply hidden insecurity that leads him to make such desperate decisions to 'become a better man'. Haruki is the opposite, a pure-hearted, suave, so-cheerful-he-hums type of guy who takes care of everyone like a supportive older brother who just want you to do your best with whatever you're doing. Both Akihiko and Haruki are the oldest in their four-man band, and it shows in how they go about their relationship compared to Mafuyu and Ritsuka.
No matter the couple though, and no matter what clichés do exist, none of the usual stereotypes or misconceptions ever come up. There are no "tops" and "bottoms", no constant sex scenes, no cheating or quarrels about a dumb misunderstanding, because the characters are just people with more going on than that. All-in-all, Given just feels more like a decent contemporary love story that just happens to involve homosexual relationships, rather than a story about The Gays™ made purely to pander to the alphabet Tumblr community.
Definitely not saying that the story doesn't have its clichés, though. It's manga/anime, so of course there will be some clichés, awkward moments, and humor attempts that don't quite land. But when it comes to modern contemporary, Given's LGBT characters are really well done. And when you look at your other choices, not just in LGBT contemporary but in the cursed lands of yaoi manga, it's one of the only ones I've actually enjoyed reading as of late.
But, again, the bar is so fucking low for this kind of shit.
