Easy there dude. Your getting a little insulting. The very clinical definition of romantic love is love with sexual desire. Look it up. It's there in black and white. Love without sexual desire is called platonic love i.e. close friendships.
I'm not saying there isn't evidence that Sakurako, and Kasumi are in love. What I'm saying is, there is no definitive proof. That's all.
I might have come on a bit strong, but that is what happens when I see terrible argumentation. So sorry~
Oho, I didn't know I was talking to a real true blooded cynic! What a delight. And by that you mean your definition, right? I don't need to repost the actual definition, @random was quicker.
Just remember that you basically just said that impotent men, people with low sex drive, asexuals and almost anybody above the age of 50 cannot be in a "solid romantic relationship" due to their lack of sex. Wanna also add that homosexuals aren't actually in real relationships because they can't procreate? Lesbian sex isn't real sex because it doesn't involve penetration? lol
Yeah, no. Sakurako literally confessed in the previous two chapters. Kasumi might be more ambivalent about it, but you'd have to be awfully cynical to think all the collective hints and realizations she had until now are not evidence enough.
