Girl you should absolutely read the novel
I wasn't bored for a single minute
It's not been long since I started reading web novels and I was hesitant at first cuz it's kinda long(800 plus chapters) but after reading it I am upset that there aren't more chapters
I mean there's the side stories but those aren't translated on the website I am reading on.
Seriously though give it a try and you won't be disappointed
About the bromance
Hyunjay literally calls yoojin his life, need I say more?

This used to be my favorite manhwa but that changed after I started reading the novel cuz the novel is sooo much better
Also the manhwa yoojin is kinda different then the novel yoojin
In manhwa he is more loud and comedic while in the novel he is more sassy and I absolutely love his inner monologue in the novel
Also the novel have sooo much bromance that you might as well call it romance
Ya guys yoojin and hyunjay are married believe me. They even have a child together
