Beautiful art and aesthetic! The characters in particular are very well drawn. My favorite part though is the theme, that having a successful relationship has so much to do with listening, and this tiny game somehow conveys just how hard that can be sometimes!
My feedback is that strictly as a game, it is very small and simple, and (surprisingly) very hard from the beginning. I'd add a difficulty curve, making maybe some of the first sequences easier (less symbols, more time to look, etc). Also, as a reward to the diligent, actual dialog in between "waves" would be interesting and add to the flavor of the game.
