Wasn't a big fan of Kaoru till 189. I mean I get that she's been a part of pushing the story along for Shizuka (and possibly Honoka and Hibiki), but till now she's been more of a plot device than an actual character to me.
But with this she's changed, reborn by Bouchan.
Kaoru has become a playful scamp, instead of being a cruel player. Looking forward to more of her now.
