These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way.

YMMV: Princess Debut
Crowning Moment of Heartwarming - At the Ball in Saint-Lyon, King Crown asks your partner how he feels about being tricked by you and the princess and if he still wants to dance with you. He says without hesitation that it doesn't matter who's real or fake, you're his partner and that's all that matters. Doesn't happen if you beat the game with Klaus or Tony, however, who never find out that you're not the real princess.
Ear Worm - Most of the songs are well-known classical or contemporary tunes, and you'll recognize most of them even if you don't recognize the title. This is followed by a song refusing to leave your head for the rest of the week.
Guide Dang It / That One Boss - Luciano leaves about halfway through the game. Getting him to come back so you can get his ending has caused many headaches.
