…where others have lined up Lisa’s past activity and connected it to another star.

One of K-Pop’s biggest mysteries is the disappearance of ex-YG Entertainment idol One (also known as Jaewon), who seemed destined for super stardom. After leaving the company in 2019, Jaewon released one album before slowly vanishing from online, with very few reports of him being seen over the years since.

Fans have used the timeline and other evidence as “proof” of his connection to Lisa, with one of his songs resurfacing.

On his last album, One included the track “Last Cigarette,” which is believed to line-up with lyrics from Lisa’s “Dream.”

I can’t save you.
I can’t answer your calls.

— Jaewon, “Last Cigarette”

Whenever I’m missing you
Call you up, but I can’t get through

— Lisa, “Dream”

Another line compared from each song talks about the break-up being hard on either party, with Lisa’s seeming to be a response.

I hope you can understand me,
Though it might be hard for you to.
Actually, it’s hard for me too,
So don’t ask me anymore, yeah.

— Jaewon, “Last Cigarette”

I guess that I’m taking what I can get
‘Cause I don’t get nothing new from your friends
If you got the harder side of the break
Then why is it harder for me to take?

— Lisa, “Dream”

A line about letting go was also compared from each song.

I can’t just let it go completely.
You have to find your own path now.

— Jaewon, “Last Cigarette”

When it ended, I kinda hoped that it’d be open-ended
But you never looked back
Well, I guess you can’t hold on to something once you let it go

— Lisa, “Dream”

These lines have fueled thoughts that One is the ex even further, with netizens discussing the possibility online and causing past connections to resurface.

Listen to Jaewon’s song “Last Cigarette”, it’s very similar to Lisa’s song “Dream” #lisa #jaewon #dream #mv #fyp
