...The hell?! Who thinks like that?! Why does this guy think comparing his lover to a rabbit is romantic?! Like, it's one thing to say, "She looks so sad and mournful, like the Velveteen Rabbit," or something, but to actively expand upon the idea that she's a rabbit by unironically thinking about giving her carrots...?

The comparison could have worked, I guess, if it were limited to his thinking she needs to be loved to become real, or whatever, but then he proceeds to ruin it by overdoing it so much.
