The real reason why something always happens two months after a President says they are stepping down

In fact, it is certain that past Presidents stepped down two months after saying they would. It seems the President let me know.
[Late July 2016, President Park Geun-hye]
Friend 1: Gaeddong, actually we are all here. Your mental illness was so severe (meaning you developed schizophrenia after failing an interview) that we have been secretly following you. Do you want to talk to the President? (Two days later)
Friend 1: Gaeddong, it's President Park Geun-hye. Go ahead and talk to her.
Park Geun-hye: This is Park Geun-hye. I am so sorry, what should I do? I will step down.
Me: Madam President, it's okay. Please don't worry about me and step down.
Park Geun-hye: Oh... haha. Okay, please stay for now.
And then, two months later, Hankyoreh broke the news about the state affairs manipulation. And in October, JTBC broke the news about the tablet PC.
President Yoon Suk-yeol also announced in advance when he would step down and left two months later.
Mid-October 2024: I will step down.
Late October 2024: I will step down.
