Singer Lee Chan-won has transformed into a witty "promotion fairy," looking after his fans' health (?) while encouraging them to watch his latest broadcast.

Recently, on Lee Chan-won's official Twitter (X), a heartwarming photo and a playful post were shared ahead of the KBS2 show 'Secret of Celeb Soldiers,' quickly becoming a hot topic.

Under the title "Efficacy of Chan-tto Teller," the post humorously claimed that simply looking at Lee Chan-won provides benefits such as "improvement of weak constitution, better blood circulation, enhanced vision, and anti-aging." It even suggested a specific "dosage"—"Watch at least once a day (as often as possible)"—delighting fans with this "Lee Chan-won Therapy."

In the accompanying photo, Lee Chan-won pulled off a dark denim set-up featuring unique patchwork, epitomizing the perfect "boyfriend look." Sporting a gentle smile and a V-sign for the camera, his refreshing visuals seemed to personally prove the "vision improvement" mentioned in the post, offering a true feast for the eyes.

With his smooth hosting skills and vast knowledge, Lee Chan-won is excelling as a "teller" on 'Secret of Celeb Soldiers.' Fans reacted enthusiastically, saying, "I’m going to get my energy boost from Chan-tto Teller today," "Lee Chan-won is a human vitamin," and "I’m counting down the minutes until 8:30."

Lee Chan-won's performance as the "Chan-tto Teller," guaranteed to wash away the day's fatigue, can be seen tonight at 8:30 PM on KBS2.
