I do hope all this Bowsette X Peach yuri gets translated, it's super cute.
I'm not great at Japanese, but i think the first panel is bowser saying he finally caught the princess. The second panel is Peach being surprised and asking if he is bowser. And the last panel is peach confirming how pretty she is because bowsette is supposed to look like her.
