The trope is okay. The deliver is not.
And it's kinda taking a turn when they have even more panels than the main couple. Like if the author want to take another turn and make the focus about them, it's okay as long as it's in the side story or stuffs. So the story kinda all over the place. With them being stubborn, denial, and etc it's not helping. Not the type of character that would make other people/readers like it. The k-readers didn't even like them that much, i rarely find comments about them. The majority just confused cause the cover, the summary of the manhwa, etc should be focused of their main couple instead.

Atp i feel sorry for second couple why yall find them annoying this kind of trope is the best you know if you can feel it
