Firstly, I need to say that I read a lot of romance, and something that really sells a good romance for me is when you can /understand/ why they fall in love beyond a surface level, and thats something I think sasamiya does so, so well (though on some level this just comes down to writing likable characters more than anything). Its hard not to love both of them and feel giddy during the moments they have together. I'm a big fan of pining, and considering the entire first half or so of the manga is 80% Sasaki doing just that (or Miyano doing the same thing not fully realising) it just hits all the right spots for me on a personal level.
On the topic of characters, I also just really enjoy how well developed the side characters are. Of course they wont be as nuanced as the leads but they do their job well, and it just really adds to the story imo. The dialogue is very realistic, and they just act pretty much like how regular teenage boys act without there being any maliciousness present.
While this mostly applies to their classmates at the all-boys school, I honestly also really appreciate the female characters that show up as well. There arent many of them and they dont show up often, but within a genre like BL where a lot of female characters can get very heavily demonized I appreciate how sweetly characters like Kuresawa and Ogasawara's girlfriend are presented despite their main personality trait being them being a fujoshi, and same goes for Miyano's female ex-crush who gets some genuinly funny moments when she shows up without causing drama for the plot.
I probably have more to say but I guess this is the gist of it. I guess if I had anything 'negative' to say at all it'd just be that I sorta understand why this wouldnt be someones thing if you're into stories with more heavy drama/higher stakes, but thats preference. To me this is pretty much my ideal romance, and I hope I can find more like it.
