Singer Sung Si Kyung serves Chinese food to the Black and White Spoon chef...where does this confidence come from?

Singer Sung Si Kyung appeared on Netflix's "Black and White Spoon: Cooking Class Wars" and defeated Chinese cuisine master Chef Yeo Kyung-rae to become the head chef of the cooking class.
On the 27th, Sung Si Kyung posted on her Instagram, "Next week, I will be serving Chinese food to chef Lim Tae Hoon and Optivert's Park Ji Hyun.
There was "Mannal Tende" where Chef Yunu joined late. I finally stopped saying I would cook and treated the Chinese chef to Chinese food.
(laughs) Both of them are very delicious people, both in terms of food. I think you'll understand if you take a look. Please look forward to it." He posted several photos along with the comment.
The published photos include a three-shot of Sung Si Kyung, Lim Tae Hoon, and chef Park Jun Woo, as well as a dish of Dong Po Po Roo (thick boiled pork) and beef with broccoli.
The post includes a variety of mouthwatering dishes, from stir-fried vegetables, stir-fried lettuce, and meringue rose cookies for dessert. Fans who saw the post commented, "Oh, I'm looking forward to it,"
Responses included, "This is a really interesting combination," and "I'm really looking forward to the rose flower meringue at the end."
Sung Si Kyung, who runs a YouTube channel with 2 million subscribers, is a foodie.
He shows his extraordinary love for food in his "Mogul Tende" cooking segment.
