Finally, the Haruka drought is over. Yeah, it did feel that long.
I'm pretty sure he doesn't even need to date Haruka to get one kiss from her, she'll gladly do it on the spot if he asked. But of course he treats her the same way he treats Saki: someone who's not even an option.
I guess it doesn't help that these two girls are cut from the same cloth: Thirsty Kazuyasexual with similar hairstyles (Saki has straight cut ends and dark irises), and also both apparently fall below his standards for boob sizes. Both girls are also level 1 bronze virgins like him unlike his level 500 predator serial cheater ex or the goblin-slaying man-eating sex monster.
Sure, both are secretly obsessed about him, but until thoughts about stabbing, kidnapping and murder shows up in the message window, I don't think they're that bad that they shouldn't count as girls to him.
