I Live Alone NCT's Doyoung Shows His Big Brother Side in Front of His 4-Year-Older Brother Jonathan

The episode of MBC's 'I Live Alone' that will air on the 13th will show NCT's Doyoung and Jonathan engrossed in studying history.

The video released before the broadcast showed a guest visiting Doyoung's house, and Doyoung caught everyone's attention by going out to greet them in front of the door wearing only socks.

The main character who made Doyoung wake up suddenly was Jonathan.

Seeing him naturally greeting Jonathan, Jeon Hyun-moo asked, "Are you close with Jonathan?" and Do-young confessed, "I saw you on TV and wanted to become close with you, so I got your number first," and "You have the same sense of humor," revealing his affection for his younger brother Jonathan.

Doyoung prepares a 'Doyoung set' for Jonathan, who said he didn't eat, by making sweet potato candy and a healthy juice with a whole ginseng root. Key is pleased with Doyoung's dependable appearance, saying, "(Among us) he's the youngest of the youngest, but he's like an older brother in front of Jonathan." They're both so cute, lol
