I don't know the context, so I can only guess, but seems like the girl on the right is an pop idol singer who performs on stage every day in a funny costume. I think she is saying that as she is made to do this every day, she has come to believe that she's enjoying it.
The girl on the right is a pop idol and she likes karate. Before this scene, she said that she was at first embarrassed at wearing swimwear. In this picture, she is saying "It's ike practicing jab every day and learning how to do it, I finally accepted this appearance."
