Actor Koo Sung-hwan has surprised fans by revealing an unbelievable behind-the-scenes story from his school days. During his high school years, he stood at 183cm and weighed 78kg, earning him a reputation as one of the school’s ‘Top 4’ heartthrobs.
On the upcoming episode of MBC’s ‘I Live Alone’ airing at 11:10 PM on the 13th, Koo Sung-hwan is seen preparing for a high school reunion gathering. He starts moving busily in the kitchen from early in the morning, preparing a cake in his own unique way ahead of the 30th-anniversary reunion. Instead of an oven, he decides to make a ‘Koo Sung-hwan style chocolate brownie’ using a rice cooker.
Reflecting on his past, Koo Sung-hwan recalls that standing at 183cm and 78kg made him one of the ‘Top 4’ figures at school, receiving a flood of chocolates and love letters during Valentine’s Day. To prove the enduring appeal of his prime ‘Top 4’ days, he focuses intensely on his appearance management.
Koo Sung-hwan sits in front of the mirror, doing facial gua sha while chanting, “Get smaller! Get smaller!” and carefully selecting his reunion outfit. He also visits his regular barbershop to request a “Brad Pitt haircut” in pursuit of looking his absolute youngest, raising anticipation for his dramatic transformation.
Furthermore, Koo Sung-hwan finds himself unexpectedly overwhelmed and emotional while writing letters to the friends he will meet at the reunion. Displaying a heightened sense of tension, excitement, and anticipation, viewers are left wondering what his true inner thoughts were at the time.
Meanwhile, the broadcast is also set to feature Koo Sung-hwan reuniting with his first love from high school. A preview clip from the previous week briefly showed him meeting his first-round former girlfriend, raising expectations for how their emotional reunion will unfold on screen.
