This is plainly stupid... Tsubasa goes out of her way to tell Aki she was never in a relationship with Toba and that she was always faithful to Aki, but based on what Aki saw, that would make her a liar. I guess it's the mangaka saying that with love nothing else matters but it would be nice to either have the couple acknowledge the "kiss" or else have Aki thinking "it doesn't matter." This looks like a rug sweep.
