Fans Say ZEROBASEONE’s Jiwoong Was Unjustly Denied K-Drama Role

Lee Jong Suk is facing controversy over his casting as the lead in the upcoming rom-com I Seob’s Romance.
The controversy began when fans of ZEROBASEONE’s Jiwoong pointed out that the webtoon’s male lead was inspired by Jiwoong. Old social media posts from the original webtoon creator showed them sharing one of Jiwoong’s albums, fueling claims Jiwoong was the real-life model for the character.
Fans quickly argued Jiwoong was the natural choice for the role and expressed disappointment over Lee Jong Suk’s casting instead.

The main lead was literally inspired by jiwoong I wonder why they had to choose someone who’s over 30 to play someone in his 20s

Many fans felt they were “robbed” of seeing Jiwoong take a role seemingly made for him.

As the situation escalated, some defended Lee Jong Suk, saying the character is actually 33 years old. They argued Lee Jong Suk’s age (36) fits better than Jiwoong’s (27).
“Someone in his 20s” mind you Iseop is literally 33…Jongsuk is 36 and closer to his age than Jiwoong at 27 but ok

Producers often pick established actors for adaptations, prioritizing experience and fit over inspiration sources. Lee Jong Suk’s proven track record in romance dramas adds weight to his selection.
This controversy highlights a common debate where webtoon fans clash over casting choices that differ from their imagined characters.
The drama over I Seob’s Romance casting isn’t over yet, but Lee Jong Suk’s lead role stands firm for now.
