Michy was indeed traumatized by the accident that happened in the radio station. Back then, the perverted radio DJ went too far outside the script and questioned the silver-haired idol about his private life, and the thing got worse when the DJ wanted to assault him.
Michy was sexually assaulted, and there were even traces of the assault on his body. That was why the idol took precautions this time so that the same accident wouldn't be happening again. He looked calm when he answered Reno's question in the radio program back then, but it turned out that the idol was also troubled inside.
It was just his acting skills that managed to hide his real feelings back then. If Michy could tell the truth, then he would say that he was anxious in the radio show back then.
