Does it really matter whether it was actual rape or not?
regardless, KimDan went through abuse and sexual trauma which are just as bad, so to the people trying to make excuses, you need to see it for what it was: an abusive and toxic situation where KimDan suffered a lot of trauma because of Jaekyung.
And yes, we're talking about a consenting adult who consented to go through all that but even when both parties are adults, there's something called "power dynamics" that sometimes may come into play. In this case, the fact that KimDan really needed the money and Jaekyung was the only one willing to give it to him at the cost of his ass is a perfect example a power dynamic where one of them has a clear disadvantage, making the lines blurry for what consent actually means. Not everything is either black or white, people.
Now, I think bottom line here is that... this is fiction, these characters aren't real, I think we can still debate these topics because they're real life problems that some people go trough and therfore they are very important
I would never root for a relationship like this in real life, but truth is that when it comes to fiction, I eat it up every single time lmaoo the more toxic they are at the beggining, the more satisfying it is for me once they end up together, but that's just my personal preference, I understand that's not everyone's cup of tea but me, personally, I'm not agains it.
