Park Seo-jin's 11kg Weight Gain Struggle: Marathon Legend Hwang Young-jo Warns Him

Singer Park Seo-jin, who reportedly spent about 100 million won on plastic surgery, faces a crisis as his weight suddenly increased by 11kg.

On the 6th, in the KBS2 entertainment program 'Mr. House Husband Season 2', singer Park Seo-jin, who recently gained 11kg, begins a full-scale diet.

Park Seo-jin confessed, "I have gained about 11kg since my first appearance on 'Mr. House Husband'," stating his current weight is 73kg. He could not hide his shock after reading comments such as, "I won't watch 'Mr. House Husband' until your old face returns," and "Now that you've gained weight, your pre-surgery face is showing." He also ate tanghulu while expressing stress, showing a weaker will for self-management compared to before.

He received a cold evaluation from Hong Kyung-hee, a dance director with whom he has a long-standing relationship. Hong Kyung-hee, who previously highly rated Park Seo-jin's dancing skills, coldly pointed out his changed physical condition, saying, "Your body is much heavier."

Shocked, Park Seo-jin sought help from the production team and decided to take on a long-term project for his diet.

Park Seo-jin, along with his younger sister Park Hyo-jung, meets the legend of Korean marathons, Hwang Young-jo. Hwang Young-jo steps in as a running coach to check their posture. However, Hwang Young-jo is taken aback by Park Seo-jin's eccentric running posture, driven only by enthusiasm, and declares he will stop coaching by saying, "Don't even think about running."

Afterward, Park Seo-jin challenges himself to his first-ever 3km run.
