"Nichkhun gets frustrated over Victoria’s change of heart"
My dictionary says that the adjective, frustrated is combined with the prepositions, at or on. Is over an option?
"The November 20th episode of MBC’s We Got Married revealed the couple moving into their new house. In order to buy necessary items for the house, the two idols decided to visit a nearby market. For Victoria who is known to supposedly like the cartoon character Pororo, Nichkhun prepared a Pororo wallpaper. However, Victoria surprisingly didn’t accept the Poporo wallpaper as she stated her change of heart, “When I was studying Korean I used the Pororo book. I never said myself that I actually liked Pororo.” "
I don't know the reason why a reflexive pronoun is used here. Without it, the meaning of the line seems to be understandable.
