This is my opinion, so hate me if you want

Exactly

I've had this opinion since day one, mc had more chemistry with Juhee

I think it's more evident in the novel. However I think the portrayal of Korean culture and it's hints toward subtle affection definitely play a role in how their romance develops. Less shown affection, and more so reserved, private and behind closed doors, even to us readers. Which can seem odd, but I actually appreciate it quite a deal. Thanks to that the main focus never deviates too strongly from the action and direct plot line

Thanks for this (=・ω・=)

Actually, I've been looking for comments saying that it's more explained in the novel cause I really wanted to know if it was the details are same for both, now I know it isn't and that's good. I'm not really into reading novels that's why...(￣∇￣")

Ah, no worries, lol. Think of the novel being a more in depth version of the characters. Webtoons represent the visualization and create a scene for you provided by the artist, however they lack the depth and details you may find in the novel. The novel is the direct opposite. You generally get a better picture painted as to how each character thinks, their tendencies, how conflict starts and is resolved within the plot that may have not been clearly interpreted into it's visual representation. Although you're left to create your own space for that visualization aspect in your head rather than the interpretation given to you by the artist or author. Sometimes it can be an endeavor worth pursuing, even if done briefly. I do recommend giving novels a try occasionally. I often get overstimulated by webtoons or reading too much over long periods of time, and the novel helps bypass this compulsion of sorts. But, to each their own. As for Solo Leveling and Jinwoo's relationship, it is slightly more pronounced and easier to read into. That being said, it still takes a backseat to the action and events the main plot follows
