Turns out there's two versions of NoGainNoLove - a 😇 version airing on tvN and a 😈 version on TVing (Prime is getting a mix of both). Here's some of the changes (courtesy of Twitter and Reddit):

When Shin Min Ah explains why she broke up with Battery guy:

😇 "If he enjoyed thrice then I should enjoy at least once. He came as if it was a public bathhouse and only showered and left."

😈 "He held me like an exercise machine and sweat alone and left"

When Heesung says goodbye to PDnim at the wedding he says he really doesn't want to leave as she is looking sexy. She replies:

😇 Your eyes are too soulless to believe you are telling the truth

😈 It is too quiet down there to believe you are telling the truth

😇 Bok on the secretary's phone vs. 😈 Fuck on the secretary's phone

Also the sex toys scene is much spicier and funnier in the TVing version. The dildos are wearing little international costumes 🤣🤣 https://x.com/vtaesgurl/status/1835715825367482482

Lolll thnx for sharing! I’m surprised prime has a censored version. The dildos were hilarious 

I have a couple questions regarding the differences and hopefully there's someone who can provide the answers.

-Are there differences in all episodes or only one or two?

-If so, what are the differences in each episode?

LOL! Seeing international costume dildos is hilarious!
