OMG YES!! So glad I found someone who feels the same way :(
Agree so much about the early reveal—I wanted it to drag out way longer because my heart hurts so bad for Doyoon Ye and his literal hellish life. It really rubbed me the wrong way that Doyoon Kim took forever to care about giving Doyoon Ye justice instead of staying hyper-focused on the ML.
And yes, the post-reveal dynamic got so boring! I really wanted to see the ML fall for this "stranger" all over again based on his actual traits, without putting his original hyung on a pedestal. It was so much better when Doyoon Kim got to see the ML's real, ill-mannered, world-hating personality instead of the fast-forward puppy-dog act.
Stuck in the 60+ chapter range too and struggling so hard to finish it!

the story was okay, but i lowkey didnt like how within only around 30-ish chapters the ML already found out that Doyoon ye is actually Doyoon kim inside his body. idk could just be me bcuz i was hoping for more development and twists in the story that eventually lead up to ML finding out about doyoon’s body swap. after the ML confirmed that doyoon ye was actually his doyoon, the story dragged on (like mentioned in the other comments) and it just became boring. now the whole premise of the body swap just feels like it got played with once and then tossed out. plus (like also mentioned in the other comments), ML feels reaaaallly bland as a character. through the whole run of the story, all we knew about him is that he’s the blacksheep of his family and MC was the one who saved his ass and now hes really inlove with MC typeshit… like bro im not even kidding but thats all ML has going on for him
