I love office romances and I like that this BL used the age-old tropes of boss/employee+enemies-to-lovers (although that was a bit shortlived) and forced proximity/cohabitation.
I think they could've exaggerated the headbutting a bit more when cohabitating and have it mix a bit with work life because for me, the characters acted to cleanly and too well-behaved. Overall I didnt have that many complaints about the story or the pacing considering the amounts of episodes!
I liked the music although sometimes it felt a little bit loud.
The ensemble cast was also fun to watch and the male leads were handsome and had pretty good chemistry!

One big minus point for me though was the big confession scene and backstory reveal in the final episode. The dialogue felt lame, stiff and not realistic. It didn't properly convey the emotions of the characters and the whole drama of SJY finding out the true identity of JHJ ended with a bellyflop instead of a magnificent dive into the inner turmoil of the characters :/
