I finished skimming through her momotalks (including her valentines momotalk), the Ui event, the first ASS event, halofes, the ASS band event and Serenade Promenade. If she appears in other parts of the game, you'll have to tell me and I'll check tomorrow.

9 lines where "romance" or "romantic" is only in the Japanese translation

Tsumugi says "romantic" only in the original Korean text and English translation. It's up to you if you want to count this one or not.

I didn't see Natsu or anyone related to Natsu say "romance" or "romantic" in the Ui event or Serenade Promenade.
