Tbh Jonggu fainting at that moment gave me such bad flashbacks, omg. Like, dog or not he was treated so badly.
The owner is just selfish, using Jonggu for his sexual pleasure until he finds someone he's not "ashamed" of.
Trying to excuse his behaviour because "jonggu is a dog" does nothing. You wouldn't abandon a dog in the street after adopting it the same way you wouldn't use someone that clearly has feelings for you for their body.
As a wise gay man once said, "All art is quite useless". All this is is a story. Stop trying to look for political correctness, a strong sense of morality or a deeper meaning. Enjoy it if you do and don't enjoy it if you don't.
Just remember that just because an author writes a character it doesn't mean they condone their actions.
Ah, yes. A dude that's not in a committed relationship is having fun with people in a noncommittal way before even meeting the person we assume he's going to date later on.
Like, bruh, if there was a contest for jumping to conclusions this comment section would get gold medal in the Olympics
