Okay, so now Ruka's falled for the stupidity that's going around...
"She wants Chizuru"
Jesus fucking... She wants a girl that loves Kazuya for who he is! Guess who that girl is? YOU, Ruka! The 'Chizuru' she loves is literally an act! OH MY FUCKING- *deep breaths* Man, it's been a long time since I've gotten mad at a manga this much. I guess the author doesn't want the manga to progress because literally any time there's a HINT of progression, something just happens to stop it so the status quo is kept - that being Kazuya and Mizuhara continuing to lie to their grandmas and everyone else for no real reason at all.
