So he doesn't find bertia's attempts to be interesting anymore or the heroine's??

I think the translation made it really confusing but from what I got from it, he had so much fun recently (from Bertia) that the Herorine’s desperate attempts aren’t interesting. I think in the original plot, the prince liked the Herorine because of those desperate attempts but now he likes Bertia instead. ٩(๑❛ᴗ❛๑)۶
I am an emotional mess right now ╥﹏╥
