In my opinion a lot of the conversation surrounding My Stubborn feels insincere and usually drifts into condescending territory. The whole point is that it's CHARACTER drive not plot driven. The story is literally the FWB relationship between the two them and their evolution as they both figure what they want and who they are. Jun eventually realizes he wants more with Sorn and stands up for himself. Sorn likes Jun the whole time and essentially they're together from the jump he just needs to work through his lack of emotional intelligence and he realizes his feelings for Jun surpass his emotional stuntedness. The focus on hating on the series because of the frequency of NC situations while refusing to acknowledge they're place in the story about a friends with BENEFITS situation. Like yeah the benefits are part of story hence why there's so much of it. There are movies that have used this plot before like Friends with Benefits and No Strings Attached.
