On Sept. 11, he uploaded a video lasting more than 40 minutes about his trip to Vietnam.
He was on a vacation to celebrate his YouTube channel reaching 200,000 subscribers. Before the trip, the singer said he was worried because Phu Quoc is an island destination and a fortune teller had advised him to be careful around water this year.
But nevertheless, he decided to go on the trip.
In Phu Quoc, after enjoying coconut coffee, the singer took part in a lucky draw and won a challenge to experience a basket boat tour on the Cua Can River.

The 45- to 60-minute tour costs VND200,000 (US$8) and includes a visit to a floating market, eating local fruits on the river, joining local residents for fishing, and watching basket boat performances.
Lee praised the scenery along the Cua Can River, said the atmosphere was pleasant, and recommended that his fans should try a basket boat ride in Vietnam at least once.
However, he became worried when the sky suddenly darkened and heavy rain forced the group to take shelter in a hut.
After the rain eased, the group of Korean tourists continued their basket boat experience. One of the tour's activities involved local boatmen spinning the round basket boats rapidly in circles on the river, making the boats whirl around. Lee quickly became dizzy and nearly threw up, likening the dizzying ride to Disco Pang Pang, a popular thrill ride in South Korea.

The singer also had a massage and exfoliation treatment, and headed to the Phu Quoc night market with VND100,000 (US$4) in hand.
There, he tried horseshoe crab, durian, mangosteen, peanuts, and seafood noodle soup. He said the crab tasted similar to lobster and he shuddered when trying durian alongside two Vietnamese tourists.
The video had attracted more than 1.2 million views and thousands of comments.
Many viewers praised Phu Quoc's scenery and enjoyed Lee's experiences, while some said tourists should avoid visiting the island at this time because it is currently the rainy season.
Phu Quoc has attracted a large number of South Korean tourists in recent years, with direct flights from South Korea to the island increasing, according to the Vietnam National Authority of Tourism (VNAT).
In 2023, Yonhap News Agency described the island as the "Maldives of Vietnam" in a report on its appeal to Korean tourists.
According to the VNAT, South Korea was Vietnam's second largest source of visitors in the first eight months of 2026 after mainland China, at some 2.76 million, and accounted for 17.3% of total international arrivals.
