Doesn't seem like you were reading the same manga. Kyuu went far above and beyond what anyone else in this manga and most other manga has done. Unfortunately it made him a more cliched character than the usual, at the same time. One person sacrificing and compromising more than the other is SO overdone and cliched, after all. But having both characters act that way would make them stock characters with no personalities. But I don't like cliches like THAT, either. Ktbn.
The great thing about stories is people can interpret many different ways. Thank you for you thoughts on my comment. ヾ(☆▽☆)
I put off reading this for a looooong time simply because I knew I was gonna get frustrated at some point. Which I did. I was like come on guys get your crap together!!! Σ(っ°Д °;)っ
BUT! The ending made it so worthwhile for the simple fact that I got to see a bit of their lives after the confession and sex. It wasn't just confession, sex, the end. Hehe! So... Great story! ヾ(❀╹◡╹)ﾉ~
