Twinkling Watermelon: Ending Explained

Why Eun-gyeol is stuck in 1995

Ha Eun-gyeol is the only hearing person in a deaf family, a CODA who hides his musical talent to keep playing the model son. After a bitter fight with his father about pursuing music, he tries to sell his guitar at a strange shop and is thrown back to 1995, where he meets his parents as teenagers. The shock is that his father, Ha Yi-chan, can hear and speak fine in this era, a hot-blooded, cartoonish kid nothing like the deaf man Eun-gyeol grew up with. His mother, Yoon Chung-ah, is a cold, isolated girl who was born deaf.

Knitting his own parents together

Eun-gyeol's real mission becomes making sure he is born at all. He helps Chung-ah's father accept her deafness and let her learn sign language, easing her loneliness and opening her to connection. He joins Yi-chan's band, and together they form Watermelon Sugar with other young musicians. A second time traveller complicates things, Choi Se-kyung, the cello prodigy, is revealed to be On Eun-yoo from the future, who came back to find her own mother's first love. Two children from the future are quietly steering their parents toward the relationships that will create them.

The accident that cannot be undone

The central tragedy is the thing Eun-gyeol most wants to prevent. Yi-chan is severely injured in a car accident while trying to save Eun-gyeol himself, and he loses his hearing as a result. This is the origin of the deaf father Eun-gyeol always knew, and the show refuses to erase it. Heartbroken that his presence in the past caused the very wound he came to stop, Eun-gyeol instead does the only thing left to him. He persuades his devastated father never to give up on music, even now that he can no longer hear it himself.

Back to the present, and the payoff

Eun-gyeol is returned to his own time. At first he is crushed that he could not save his father's hearing, but he discovers the timeline absorbed his real gift. Yi-chan still pursues music, overcoming his disability, and the band stayed together through the years. The point was never to rewrite the past into something painless. It was to let Eun-gyeol understand his father as a person, see the love and resilience behind the silence, and stop being ashamed of where he comes from. He reunites with Eun-yoo in the present, the two time travellers landing home.

The Final Image

Back in the present, Eun-gyeol finds his father's music intact and the band still together, and reunites with Eun-yoo, the journey having changed him rather than the timeline.

Lingering Questions

Does Eun-gyeol stop his father from going deaf?

No. Yi-chan still loses his hearing in a car accident while saving Eun-gyeol, so the deafness Eun-gyeol grew up with remains. The journey changes how Eun-gyeol understands his father, not the outcome itself.

Who is Choi Se-kyung really?

She is On Eun-yoo from the future, another time traveller who went back to find her own mother's first love, mirroring Eun-gyeol's mission to protect his parents.
