I came across Grapara! a while back. I really liked the characters' dynamic, and the whole concept of an idol who can't bring herself to say no and ends up in increasingly compromising situations was incredibly exciting to me. There had already been quite a few attempts to make Sakura cheat on Shinobu (more or less against her own will), but I wanted to believe it would never actually go that far.

Then I suddenly started seeing people everywhere talking about Chapter 129, so I went back to read it... and wow. The author really went all the way.

My heart has been racing every time I think about it since then, and I almost have a hard time rereading that chapter. It's exactly the kind of betrayal that I find both incredibly cruel and utterly fascinating at the same time. Experiencing that kind of emotional shock reminds me that, in a well-written story, anything can happen, and that we're not supposed to be protected by predictable storytelling conventions. I really admire the author for having the courage to do that.

I have a feeling Chapter 131 is going to be even worse... and I can't wait to see it, even though I'm honestly terrified.
