Nope. If I remember correctly, the author had intended Jw to be the endgame since the beginning. Many fans were rooting for TK actually and I think they even sent death threats to the author but her backbone's so strong that she stuck to her idea till the end.
ps:Takuto is not chopped he my og pretty boi
Author def wanted JxH and i think they do deserve each other. It was already implied on the beginning idk why people thought otherwise lol. Although at some part, i think Taku deserves a much better guy and his character is interesting so I wished the author dwelved more onto that.( Although i ship JxH I love taku's design more than them lol he's so gorgeous, but i do respect that we all have different perspective)

Why are people so hooked on taku?? He’s so chopped lol Between haesoo and joowon, haesoo clearly had a fault in all the complications too. They were both vague af so i dont get the hate just for J.
But to be honest, i wonder if author intended it to be TxH at first then last minute switched to joowon. Cause the whole story, taku and haesoo had more sex than joowon haesoo ever did. It was more flashbacks with them to the point i need more side stories of JxH together.
