Remembering now why I don't really consider this a top favorite manhwa. The final volume honestly got a little bit boring.
The big drama here is that Seunghyun gets rejected during what should've been an absolute shoe-in of an interview process, due to Mr. Choi pulling some strings with a friend of his who was on a particularly crucial panel. Kim Jongchan sets out to fix it, furious with himself and with the company for clipping Seunghyun's wings due to something that wasn't his fault. After all, the only reason he failed the first round was because of petty office politics with people who hate Kim Jongchan for his success.
I...didn't fully get all of the reorganizing that happened as a result. Honestly, my eyes kind of glazed over during the business talk, because it just wasn't conveyed in a very interesting way. Kim Jongchan shows up at the CEO's house to ask for the promotion he's spent years turning down, which was somehow part of the reason for everyone resenting him. He was far more qualified and talented than the people (like Mr. Choi) who were technically his work superiors, which made them itchy with insecure jealousy.
Except he accepts a transfer to the sales department, since the CEO can't boot Mr. Choi out to replace him with Kim Jongchan...plus he doesn't want to give Kim Jongchan the opening to "form his own gang." But then he ends up creating a new team that's of equal status to Mr. Choi's, promoting Kim Jongchan to team lead, and letting him transfer over other employees at will (like Jiyeon) and hire contractors (like Seunghyun, who can't be an official employee until the next year's open recruitment, but who can be paid an employee-level contractor wage until then).
So how was this not forming his own gang??
The story cuts off short there, with Seunghyun and Kim Jongchan being happy that they can continue working together, but with nothing at work truly resolved, because they still have to interact with the jerks who put them in this position to begin with. Plus they have to pull in new clients and come up with new projects, which is all just glossed over as something Kim Jongchan will easily be able to handle.
(Confusingly, I swear I remembered a plotline where Kim Jongchan's clients all kicked up a fuss and wanted to stay with him, or follow him to another agency he formed for himself, but I must be remembering another story. I guess they start to meld together after a while.)
One thing that annoys me about manhwa as a genre is that the main story so often "ends" before the actual ending...which comes in a "side story" that can be fairly crucial to the primary plot. After four side stories that are just...a single long smut scene...we get a final chapter that jumps forward in time a bit, with Jiyeon finally finding out that Seunghyun and Kim Jongchan are dating, and a quick summary of other work upheavals that've happened in the meantime.
Like Mr. Choi getting booted out after all, for fraud, and the CEO (I think?) being let go in a round of executive team layoffs. Which is a wild thing to include for no particular reason. If the company was this volatile then why didn't Seunghyun and Kim Jongchan just split off and go somewhere else?
It is still a decent story, and the earlier chapters have some really good stuff, but this conclusion just overall wasn't my favorite. Plus all the smutty scenes were shading more into the "no I don't like it" "quiet, I can tell you actually do" exchanges that I don't particularly love. I did like the moments of tenderness that were mixed in, and I wish there'd been a lot more of that. That was the dynamic I'd liked so much with these two.
