[Financial News] Family medicine specialist and entrepreneur Esther Lyuh has revealed the hygiene habits of her husband, former physician and broadcaster Hong Hye-geol.
The couple appeared on KBS2's 'Problem Child in House,' which aired on the 1st.
On the show, they shared an update on having moved back in together after five years. Asked how she felt about living together again, Esther Lyuh hesitated briefly before saying, "I'm glad we're living together again. For starters, I don't think we can share a room, and I wish he wouldn't come into my bathroom."
Esther Lyuh also opened up about Hong Hye-geol's usual hygiene habits. She said, "My husband uses three towels after showering and throws all the used towels around. Since they're damp, mold grows."
She continued to complain about his bathroom habits. Esther Lyuh said, "None of the toilet lids in the bathroom are closed. Even after urinating for 33 years, my husband still doesn't flush," surprising the cast members.
Hong Hye-geol responded, "It's completely a habit. Of course I flush after number two. I've never flushed after number one," adding, "Urine is sterile. It's not harmful."
The MCs were baffled by his response and asked, "So that's why you don't flush?" Hong Hye-geol cited thrift and frugality as the reason he does not flush.
Hong Hye-geol also expressed a sense of injustice over criticism of his towel use. He said, "My wife is detestable. What has she ever done for me? Our housekeeper does everything for us."
The couple also revealed that they had never kissed in their 33 years together. Esther Lyuh said, "We're both sensitive about oral hygiene," adding, "If I try to drink Hong Hye-geol's coffee after eating kimchi, he won't even let me touch the straw."
Esther Lyuh and Hong Hye-geol are alumni of Seoul National University College of Medicine, with Hong Hye-geol one year ahead of her. They married in 1994 and have two sons.
