President Yoon Suk Yeol spent his third Lunar New Year holiday in office at the Seoul Detention Center, marking the first time in Korea's constitutional history that a sitting president has spent the holiday in detention.

According to Yoon's defense team, the president spent the final day of the holiday at the center, where his legal counsel visited him to discuss strategies for the upcoming trials.

Having been indicted by the prosecution on Tuesday for charges of leading an insurrection with his short-lived martial law imposition, Yoon could face trial and stay at the detention center for up to six months. His legal team plans to request bail after the holiday.

If granted, the president will be released upon paying bail; if denied, he will remain in custody throughout the trial, which is expected to last for up to six months.

Following the Lunar New Year holiday, trial proceedings for Yoon are expected to intensify.

In addition to the ongoing impeachment trial at the Constitutional Court, the Seoul Central District Court is expected to officially assign the criminal case against Yoon — charged with being the ringleader of an insurrection — to a court panel as early as Friday.

The Constitutional Court is scheduled to hold its fifth oral argument on the impeachment case on Feb. 4 at 2 p.m., 12 days after the fourth hearing on Jan. 23. For the sixth to eighth hearings, set for Feb. 6, 11 and 13, the court plans to hold full-day sessions starting at 10 a.m.

If both impeachment and criminal trials proceed simultaneously, Yoon may be required to attend hearings three times a week, traveling between the Constitutional Court and the Seoul Central District Court.

Meanwhile, presidential chief of staff Chung Jin-suk, along with key former and current presidential secretaries, are coordinating their visits to Yoon in the near future.

Their visits have become possible, as the Corruption Investigation Office for High-ranking Officials lifted the restriction on nonlawyer visits to Yoon on Jan. 24, allowing general public visits after the Lunar New Year holiday.

A senior official from the presidential office said, "We believe it's our duty to pay a visit to the president."

Key ruling party lawmakers, including ruling People Power Party floor leader Rep. Kweon Seong-dong and Rep. Yoon Sang-hyun, are also coordinating schedules for visiting Yoon sometime next week.

"Considering that the president is in a difficult situation, it is the right move to fulfill our duty as human beings," Kweon said on Thursday.

However, given that public visits are limited to only one per day, the specific timing and details of the politicians' visits remain undecided.

First lady Kim Keon Hee has reportedly remained at the presidential residence in central Seoul's Hannam-dong since the debacle began with Yoon's declaration of martial law on Dec. 3.
