”SHINee” key, crisis of participation in ”Mr. Trot”... What is the problem that caused panic over ”keyword”?

SHINee's Key couldn't hide his confused look when TAEMIN's song was put up as a question. 294th episode of the tvNtvN variety show “Surprising Saturday” aired on the 16th
The episode consisted of a trip to find food at Busan and Haeundae markets with TVXQ, which marks the 20th anniversary of its debut and will be appearing in its entirety.
On this day, TVXQ, who was introduced as the main character who led the unique K-POP syndrome, opened their doors with a scene where they performed a new song on stage.
BOOM said, ``Recent singers are better than M COUNTDOWN (Surprising Saturday),'' and even earned the grudge of all the performers.
After the performance on TVXQ, Shin Dong-yeop was shaking and Nucksal wondered if he had been electrocuted.
He showed a skeptical attitude. The song for the first round was "Guilty" by TAEMIN. In response, Key panicked and said, ``I'm sweating.''
BOOM revealed, ``It's a song that Mr. Key did a challenge with Mr. TAEMIN,'' to which the cast members responded, ``Of course they would understand.''
We looked forward to seeing Key's success. BOOM mentioned Changmin, saying, ``I know he has a lot of love for his juniors,'' and Changmin replied, ``I'm always watching over him from a little distance away.''
The aim was to elicit a reaction from the cast members, asking, ``Why are they watching from a distance?'' As if to prove this, Changmin said to Key, who expressed confusion throughout, ``I decided to go see a house that was on fire.''
"I'm going to do it," he said, showing off his special sense of variety. When the question came up, Key teased the round, which was not easy, holding his head in agony.
Key also makes people laugh by showing him keeping the PO (Block B) in check, who has ensured the amount of dictation.
Regarding Key's simple dictation, Key frankly confessed, ``I mainly listen to the challenge sections of my (SHINee) members' songs.''
Key's ordeal didn't stop there, as it was revealed that the main character of the one-shot was PO, much to Key's bewilderment.
Nucksal told Key he would give him ``10 years in prison,'' which sparked Key's complicated feelings, and Key expressed a sense of self-destruction as he tried to remove the microphone.
However, Key's performance stood out. When Key was called to the correct answer zone, BOOM said, ``Mr. TAEMIN also thought that he would watch the program at home.''
Key replied, ``Even TAEMIN won't be able to guess my song.'' BOOM couldn't hide their laughter, saying, ``Mr. Key is very sensitive.''
Key, who tried again, expressed his sense of relief, saying, ``I did my best.''
BOOM asked, ``If you make a mistake, will you challenge Mr. Trot?''
He asked a lot of questions, which elicited a lot of reactions from everyone. However, when the correct answer was confirmed, Key got angry and said, ``I don't want the members to sing songs again.''
