Ngl, I do a little dance any time A.C.E comes up. I stand hard.
That aside, I love how, in two 15-ish minutes episodes, we got so much story already. Korean dramas do cram in the story. I like how they circled back to show the full scene of that confession.
If you get a chance, you should check out Once Again. It's got the main lead from The New Employee in it. Also, if you ever get a chance to read the manhwa for that, it's so good.
