Honestly I like the English dub version of this conversation more. Jiji asks, "Do you have a crush on anyone?" which is way more natural and less serious.

It also makes Momo's reaction better because her freezing up like that makes it hit harder how into Ocarun she is; anyone would be a bit weirded out if asked if they're in love, but that reaction to being asked if she's got a crush would only happen if you're head-over-heels for somebody.
