I personally loved this manga—except for the end. As some people have mentioned, if you're looking for ecchi, it's there, just not at the end. MORE IMPORTANTLY, at the end, the story feels rushed/broken. The whole plot is set up well through hundreds of chapters (albeit with SO MANY common tropes in terms of the romance, it can be kind of painful). The last couple of chapters/last volume or two just aren't it for me. Yes, everything in the end is resolved well, but it feels like the story ends when the two MC's admit their feelings—the author tried to have a lot happen after, and it really was, for lack of a better word, crap. Literal crap. I would suggest stopping reading when the two MC's are finally together: anything beyond that, and you'll be dissatisfied, unless you're like 11 or something. As well, there is NO side character development. No other relationships, no character backstories, nothing. Once again—if you're in it for action, this isn't the right manga for you. Its 140 chapters of painstakingly slow MC development (can you even call it development?). Those who liked the last couple of chapters most honestly shouldn't be reading this manga, tbh.
