It’s crazy how incredibly rare it is to see two couples interacting like this in modern Manga. If this was more Comedy focused, male friends would just disappear, that screen time would be dedicated to introducing another love interest into the Harem.
The only other dudes you see are random street punks who attack the heroine (happens in every one) or their direct family. But look what we lose! Back 20 years ago, having a cast of diverse characters to match up was the appeal! Romance charts! Not just a single dude with a huge harem, friends! Chandler and Joey not just Joey hooking up with girls… oh god modern manga is the spin off“ Joey”
To be honest, I make a point to almost exclusively read or watch stuff I know is focused on a distinct pair of characters trying to get together, and their supporting cast that might include more pairings. I can count the number of actual harem stuff I've consumed on one hand, I feel like. Okay, might exceed that count a bit if I go far back enough, but most of the stuff I watch or read now is like that, such as this, Kimi ni Todoke, ToniKawa (if there ever is goofy love triangle shenanigans, it's generally short-lived lampshading and expectation subversions by Hata-sensei, and almost exclusively focused on secondary couple pairings, Like Aya-Ginga-Shirogane, since the main couple is backed up by a legal document from as early as the fourth chapter and/or first episode), HoriMiya, SukiMega Dangers in My Heart (BokuYaba), Alya (Roshidere)...
The only 'harem' I recently watched and then read was Nisekoi (about a decade old, I think, at this point), but it was clear to me from early on it was really just a stretched-out love triangle with a couple of losing heroines attached. And even the love triangle felt like a bit of a farce to me, since
the girl the guy supposedly had a crush on from the start had static to glacial progress with him the whole damn way, to the point I knew she was on the losing track, and I realized
the girl he was forced to be fake-dating was the real romance end-game by the end of the anime, and so I knew going into the manga she was the one to pay attention to, and the other was just a distraction.
Okay, that's a lie, I also watched the first season of 100 girlfriends, but that's not really a standard harem, either. When all the girls win, is it really the usual harem nonsense? But it becomes a different kind of absurd that's amusing in its own way.
Oh yeah, I ended up watching Haganai at some point because I figured some saw it as a classic for a reason, and deeply regretted it. Ended up looking into stuff about how the manga progressed, and it sounds like a right mess. I'll just assume the male lead kept his promise to
Sena to date when they both go to University and leave it at that, because the alternatives all feel like such bullshit.
