Calm your shits down, their story is not finished yet. No need to diss Fargo because you don't like the side stories. If you're contented with the original couple, drop your shitty thoughts about the side stories because Fargo doesn't need a person telling him/her to stop. This is her story, she writes it the way she wants.
Also, i'm the one who didn't calm my shit lol (〜 ̄△ ̄)〜
I agree that Fargo does put too much side story in her manhwas and that they should be considered story arcs instead. If You Hate Me So was also long asf the story ended with 20+ chapters and the side stories occupied the rest until 40 or 50 but it's not a bad thing. It's actually nice in my opinion because she shows the lives of her other characters aside from mc and that would explain their personality more.
Not gonna lie, Fargo is not good in storyline. I mean what the hell is that, this new side story is lame. The way they fell in love was too fast an in such unusual way. Chowon was all over dojun since many years and he forgot him in less than 3 than weeks!@#$???? It does not make any sense. Him acting like that his really ooc. Also Fargo is seriously putting too much side story, like damn. There's like more than 50 chapters of them. It has been 1 year since this manhwa officialy ended, like girl stop. Her storyline are really wack, sorry not sorry. Hope she will be better in future bcs her drawing are amazing. ┑( ̄Д  ̄)┍
