Don't kill me: the manhwa did a great job showing what a relationship would look like if the couple has polarising love languages, and that a person's personality doesn't just do a complete 180 once they're in love.
I also find it Frustrating that Yeo-won(the boss, top) is still bit of a douche dating Seok Yeon(bottom)..but then you see Yeo-won sharing something of his past or his thoughts with Seok Yeon that you just know he hasn't shared with anyone else. He has also opened his home to Seok Yeon even tho he's a very private individual and has essentially given him free rein. Personally, that says a lot. Actions>>>words
They have softened around the edges since dating (IMO the epilogue needs more tenderising) but at the very core, Yeo Won is still a pragmatic emotionally-repressed workaholic and Seok Yeon is an idealist with a somewhat rose-tinted perception of love.
Idk, I guess I'm impressed? Author had the guts to stay committed in leading the story with their personalities over a preconceived notion of what BL romance is supposed to be til the very end. (Plus it makes their banters and interactions so much more interesting than I wuv you kiss sex kiss i wuv u more sex)
