”NCT” Do Yeong transforms into a reliable older brother in front of Jonathan! Treating him to a ”Do Yeong set” = ”The happy life of a single man”

Do Yeong of the boy group "NCT" will show his "big brother-like" side in front of Jonathan, who is four years younger than him.
In the episode of "Single Man's Happy Life," NCT's Do Yeong and Jonathan are shown engrossed in studying history. Jun Hyun Moo commented, "Jonathan and Do Yeong are naturally exchanging greetings."
Are you close with Nathan?" Do Yeong replied, "I saw him on the show and wanted to get closer to him, so I asked for his number for the first time. We have the same sense of humor."
Do Yeong responded to Jonathan's request that he not eat rice by making him some sweet potatoes and sangsam (wild ginseng).
They even made a whole bottle of healthy juice and prepared a "Do Yeong set." Key (SHINee) said, "I'm really the youngest among the youngest, but in front of Jonathan,
He's like a real big brother," he said, smiling at the reliable Do Yeong. Jonathan was surprised by the delicious-looking sweet potato and said, "It's really hot!
Be careful!' Do Yeong warns him, but he says, 'It's okay,' and tastes it. Then, he is at a loss as if his mouth is on fire.
Jonathan's reaction to the question makes people laugh. Meanwhile, Do Yeong and Jonathan's best friend chemistry can be seen on "I Live Alone," scheduled to air at 11:10 p.m. on the 13th.
