“Defo a kpop singer” — Fans go wild over "You stole that line from me" lyric in BLACKPINK’s Rosé's 'Rosie' album, guessing ex's identity

On December 6, 2024, BLACKPINK’s Rosé unveiled her highly anticipated debut solo studio album, Rosie. The 12-track album marks a significant step in her solo career, following the success of her 2021 single album R. While Rosie boasts a variety of musical styles, much of the public's attention has focused on its deeply personal lyrics inspired by a past toxic relationship.

During the album's promotional interviews like Apple Music's The Zane Lowe Show, Rosé revealed that many of the tracks on Rosie were influenced by her personal experiences, particularly a toxic relationship she endured in the past.

The track toxic till the end drew particular attention for its raw and honest depiction of an unhealthy relationship. In the Apple Music interview (December 4), Rosé revealed that the song was initially titled The Ex, but she opted for the current title as it better captured the emotional intensity of the lyrics.

Fans quickly speculated about the identity of the ex-partner who inspired the song, with some assuming the person might be a fellow K-pop artist due to Rosé’s close connections within the industry. Their speculations are based on the lyric:

"Now he's on the screen saying "Don't leave." You stole that line from me"

Netizens tried to find the line in other male K-pop idols' songs and came up with hilarious speculations citing potential candidates like NCT's Johnny, GOT7's Mark, and more. One fan wrote on X:

"her ex is defo a kpop singer... cause"

Fans commented that the fandom (BLINK) needs to get to the level of Taylor Swift's fans to come up with suspects. Some fans joked about how her ex could have been GOT7's Mark or the South Korean singer Loren (under The Black Label).

"Blinks need to get on the Swifties’ level, cuz they would’ve gotten at least 3 suspects by now," one fan joked.

"Call me a delulu but loren's recent songs sound like something you can sing back & forth w her new album... just sayin'. i'm convinced it's him since they were so close 2 years ago and then suddenly they're not. Plus he's got a tattoo that says "GAME OVER"...game...boy?" another fan shared.

"Wait is it Got7 Mark there was a rumor about him one time," one other fan added.

However, a few fans speculated in a lighthearted manner that it could also be South Korean idol and actor Cha Eun-woo or NCT's Johnny.

"My interpretation was her basically saying he’s calling her on the phone (or text) saying don’t leave & when she says you stole that line from me was her saying that she would tell him not to leave & now he’s the one saying that to her in a way of convincing her to stay with him," one fan commented.

"What if it's Cha Eun Woo? maybe it's just my gut tho hmm," another fan joked.

"omg guys its johnny i cracked the code," one other fan said.
