Bona is on the verge of becoming a hate character, claiming Victor Osimhen for Kim Tae-ri's gold medal.
In the 7th episode of TVN's Saturday Drama 'Twenty Five Twinty One' (playplayed by Kwon Do-eun/directed by Jung Ji-hyun), Na Hee-do (played by Kim Tae-ri) and Ko Yu Rim (played by Bona) became the support numbers for the Iron Stream.
On the day of the broadcast, Na Hee-do and Yu Rim confronted each other in the Asian Games fencing final. Many people won the title of the high Yu Rim in the match between the gold medalist Yu Rim and the new Na Hee Do, but the results were different. Na Hee-do won a gold medal by winning a point in the last round of the game. But when Na Hee-do cheered for the gold medal, Yu Rim swept the atmosphere by protesting to the referee as Victor Osimhen.
In the end, Na Hee-do said, "Did I have to give it to you today, because I want to see Yu Rim win?" And Yu Rim said, "What did you just do? What show did you do?” Na Hee-do said to the high-ranking Rim, “You’re Victims? Why are you having a trial now? “It happened when you protested like crazy and cried on the podium.”
However, Yu Rim said, "It is the right of the player to appeal to Victor Osimhen." Na Hee-do said, "It is also the player's duty to accept the judgment. You shattered my gold medal. My gold medal lost its honor because you didn’t acknowledge the result.” “So you’re angry,” said Ko Yu Rim. I am more divided than I am when I lost the gold medal, "and Na Hee-do said," Do you think I lost the gold medal? I am the one who lost the gold medal.
The gold medal that Na Hee-do made with his sweaty efforts was ruined by the tears of Yu Rim. Later, Baek Yi-jin (Nam Joo-hyuk) gave Na Hee-do a boost by giving an exclusive interview that the referee's "the players can mistake themselves for being quick in a state of excitement, but I am not mistaken," but the relationship between Na Hee-do and Ko Yu Rim became irreversible.
