Yena and Sun-jung are my daughters

Origin

“Yena is Seonjeong’s daughter” is a line from the MBC daily drama Maybe Love (Sarang Haenna Bwa). The series aired weekday mornings at 7:50 a.m. from 15 October 2012 to 3 May 2013; planned at 125 episodes, it was extended by 19 and ended at 144. It followed a woman whose life falls apart after her best friend takes her husband — the lurid register typical of Korean morning dramas.

The scene in question comes from episode 120, broadcast in April 2013. Park Do-jun (Park Dong-bin) learns from Han Yun-jin (Park Si-eun) that Joo Ye-na (Kim Na-hee) is the daughter of Choi Seon-jeong (Kim Bo-kyung), and with his eyes bulging he lets the orange juice he was drinking pour straight back out of his mouth. The Korean phrasing invites a misreading: the line does not mean “Yena and Seonjeong are my daughters,” but “Yena is Seonjeong’s daughter” — a revelation about a hidden parentage.

What made it a meme was the reaction, not the line. The trajectory of the juice, the eyes about to pop, and the needlessly solemn score laid over it all sent the intended shock rolling in a completely different direction. According to behind-the-scenes footage, the juice was not in the script at all — it was Park Dong-bin’s ad-lib.

Spread

The clip circulated in Korean communities as screencaps and short videos, then crossed over abroad on 2 May 2013 when the American games-and-culture site Kotaku ran a roundup of reaction shots from Maybe Love. Kotaku also noted that the clips were being recut as dubstep and PSY remixes. This is the period when the scene became known, on its own, to viewers who had never watched a single Korean morning drama.

Because far more people knew the scene than the show, Park Dong-bin picked up the nickname “Juice Man,” and it followed him as a standing epithet thereafter. He died on 30 April 2026, and obituaries still identified him as “Juice Man.”

Variants and derivatives

The meme did not trend once and vanish; it resurfaced in a new shape each time the dominant medium changed.

• At the second ranking announcement of Mnet’s Produce 48 in 2018, trainees from Yuehua Entertainment re-enacted the scene. It drew extra attention because one of the trainees taking part was named Choi Yena.
• In 2022, TikTok and YouTube Shorts filled up with videos that played the “Yena… is Seonjeong’s daughter” audio and filmed a dog or cat reacting. Here the original characters drop out entirely and only the reaction structure survives.
• The juice-spitting frame has been detached into a generic image for an exaggerated reaction, used in situations with nothing to do with the line.

How it is used

Either half works on its own. The line alone signals that whatever is being revealed is that far out of nowhere; the juice frame alone reads as “this is the face I made on hearing it.” The loose sentence structure, which lets you swap in any pair of names and any relation, is part of why it has lasted.

• Pairing the line with the juice frame on hearing an unexpected fact or twist.
• As a reaction image standing in for a shocked face.
• Swapping the names — “X is Y’s daughter” — to mimic a relationship reveal.
• As the go-to example when discussing makjang, the deliberately outrageous Korean melodrama style.
