She has no way of knowing how incredibly complicated the topic of Aqua’s favorite idol actually is. Would it be the young Ai that inspired his patient? How about the one that fought to raise a family despite the incredible repercussions that would happen if it came to light? Perhaps the sister that he grew up with and strove to follow in her late mother’s footsteps? Or, would it be the reincarnated patient of his that finally achieved her dream, once impossible?

My point is that if Kana manages to become Aqua’s favorite, then he will have truly fallen head over heels for her.
