Thank you for the rec! I just finished reading the available chapters and good lord, it's refreshing to see a level-headed MC that ain't righteous goody-two shoes. He made necessary sacrifices and be selfish when required and I couldn't ask for a better MC. I always hate goody-two shoes MC that acts like they can save everyone even though their actions will only hurt people once you step back and see everything in a bigger picture.
Glad you enjoy it! It is totally worth the read. The novel is completed too and it is the most popular novel in Korea. I seriously recommend you reading the novel if you want, for a better understanding and well, feels. The mahwa is good at capturing their characters so far and follow the plots nicely. The novel also focus on the development of the characters including the side ones. All of the characters are very loveable and despite the original MC (YJH) kinda jerk-ass personality, he will be better! And of course the main MC (KDJ) is very smart and cunning to utilize what he read for his schemes which is very refreshing to see
Spoiler ~ i dont remember all of it tho
He sacrificed himself again.. but it kinda ends on a hopeful cliffhanger.. basically he made another avatar of himself but they rescued him so he's in coma-ish... they're trying to gather his story,, basically his dreams so he will wake up again... the ending is the stories started to gather n they open the door of the room... that's it i cried and screamed

...surprisingly good. Every manhwa (of this concept and has a male lead) that I came across before this is super cringy and the MC isn't even likeable. But dang, Cale is likeable, smart and not to mention, hot too.
Can't wait for an update!
