What? The ending may not be the greatest thing ever but it was pretty decent and fits this series quite well, the author at least confirms that they're practically a couple in all but in name and will officially date once shounen is older, with the plus of shounen basically implying that he will definitely f**k onee-san once that time arrives, that's definitely a lot better than an open ending where the status quo isn't changed. Plus, there's always a chance of the author going back to this later since he left enough room for a sequel or extra chapter in case he wants to do it.
Well, when i read chapter 37 i sure as hell didnt know that this was gonna end in 2 chapters.
The overall series was great, but ending is pretty cliche tho: "it was my first time, i'll wait for you, blablablah".
