I've seen this on the internet in general over the past few years, and there seems to be an unhealthy fixation on judging other people's personal tastes as somehow objectively wrong or correct. Nobody's personal tastes are ever wrong. This is something everyone needs to accept. If this is your idea of a joke, it doesn't come across that way.
It was very obviously a joke, and they're fictional characters. Calm down.
I like this series, and I also liked that there wasn't a clean and simple "solution" to the crush. That's how love works sometime.
Also yay, stuff is working out for Rika, that's a happy ending.
