Actor Park Bo Gum has revealed that he personally shaved Kwak Dong Yeon's head before his military enlistment, sharing a funny behind-the-scenes story about how he prepared for the special moment.
On November 9, tvN Joy released a new video for the upcoming variety show Bo Gum Magical 2, featuring Park Bo Gum and Lee Sang Yi reuniting ahead of the show's second season.
During their conversation, the two actors recalled how Park Bo Gum had helped Kwak Dong Yeon, the youngest member of the first season, prepare for his military service by cutting his hair.
Lee Sang Yi explained that he had been busy with filming projects and practicing nail art, which prevented him from joining them that day.
He then asked Park Bo Gum, "How many millimeters did you cut it to?"

Park Bo Gum casually replied, "3 millimeters."
However, Lee Sang Yi revealed that preparing the haircut had been more complicated than expected.
He asked whether the hair clipper Park Bo Gum originally brought had a different length setting and recalled hearing that it was missing the necessary attachment.
Lee Sang Yi explained, "Our manager's friend runs a hair salon in downtown Muju. Apparently, someone contacted the salon and said, 'We're going to shave Kwak Dong Yeon's head, so could we borrow a hair clipper?'"
The unexpected story made Park Bo Gum burst into laughter.
He responded, "How did that story reach only you? I really struggled to borrow the clipper attachment. Thank you."
Their conversation revealed the effort Park Bo Gum had put into preparing the haircut for Kwak Dong Yeon before his enlistment.
The story also highlighted the close relationship between the cast members, who previously worked together on the first season of Bo Gum Magical.
Meanwhile, Park Bo Gum and Lee Sang Yi are preparing to return for Bo Gum Magical 2, which will feature new activities as they get ready to open their second shop.
The upcoming season is scheduled to premiere on November 29 at 7:45 p.m. KST.
