When people said this drama was moving too fast, they weren't kidding.

Day 1 - FL meets ML for the first time on a rooftop of their workplace, and he kisses her without her permission or any indication at all that she's interested. They then proceed to have a full blown makeout session, since she doesn't complain, so there's that, I guess.

Day 2 - ML moves on with his life and tries to do his job, while this naive Mary Sue follows him around, harassing him in front of other workers, and generally acting like his wife - asking him if he's fine, then straight up telling him he's not fine, that he's overworking himself, and that he needs to eat something (after which she forcibly feeds him a candy). Keep in mind, at this point she has only known him for ONE DAY.
He, in turn, gets all raw and emotional (instead of weirded out, which he should be), and opens up about his struggles. Or he's supposed to, but you'd never be able to tell based on his stony expressions.

Day 3 - they sleep together, move in together (yes, really!), she tells him she loves him, he tells her he loves her, and that she's the one he's been looking for his entire life.
Reality check: you have known each other for three days, and there's seven more episodes to go!! Which they, of course, fill with an unnecessary love triangle, a jealous ex-gf, and a subplot of this guy being some mysterious phantom, even though everyone can clearly see him around ALL THE TIME.

Honestly, everything about this show was weird: from the way they pronounced Momoko's name, to all the characters being one dimensional caricatures - the female coworkers all had the same hairstyle and only existed to fawn over hot guys, while the guys were hot and only existed to try and steal the FL away from the ML.

And somehow, despite all of that, the FL still manages to be the downright most boring character of all. The most bland and insipid Mary Sue you've ever met.
She's timid, meek, and naive, and comes off as simpleminded, to be honest. Her face is stuck in a constant state of anxiety, and her only personality trait is that she constantly worries over people being cold and hungry, like an 80 year old grandma. She has absolutely no redeeming qualities to attract anyone ever (let alone this many male characters), and she's so bad at completing tasks that you'll wonder multiple times throughout the show how she was able to hold down any job at all.

Sure, compared to most J-dramas there was a lot of kissing scenes.
Were they hot/racy/steamy as the other reviewers seemed to imply? No.
Were they worth this high of a rating? Definitely not.
