Aaah, jdramas...it's been too long.
Hotaru is a cool, efficient, elegant, collected office lady in a prestigious firm. At work, she's calm, perfectly groomed, and always prepared. At home, she's a total and complete slob. She wears ratty clothes, has manga piled everywhere, leaves her clothes all over the apartment, and talks to stray cats. No one in the world outside her home will ever see the real Hotaru. Except that one day, her landlord's son, Takano, not knowing his father is allowing someone else to live in his childhood home, decides to move in.
Problem A: Hotaru doesn't actually rent the house, she's just allowed to live there as long as she wants.
Problem B: Takano is her manager at work.
Needless to say, Takano, who is extremely neat, serious and organized, has some problems adjusting not only to the mess his home is in, but also to the difference between the public and private Hotarus. Soon, however, after some issues such private articles of clothing being left out and gourmet cheese being eaten as a midnight snack, the rules of cohabitation are established and Hotaru and Takano are somewhat peacefully coexisting and becoming friends, with Hotaru helping Takano deal with his separation from his wife, and Takano somewhat grudgingly helping Hotaru move forward with her blooming romance with another coworker, Makoto. It is, of course, rather obvious where it's going.
I think that if you liked
Sapuri/Suppli, you'd like this. Aside from the obvious office romance similarities, they also have similar themes of looking past the cute and fluffy crushing for the better, adult love, as well as both parties growing up and becoming comfortable with themselves and each other, and who they are. It's a romance, but one where both parties grow up.
The only problem is Makoto. All the women in the office are crazy about him, and I can't tell why. He's pretty nice looking, but no more so than any of the other men in the office, and less so than some(like Takano.) There isn't really anything about his personality that stands out, either. He's nice, but mostly just kinda...there. It wouldn't stand out as much, except that pretty much everyone in the office is pretty cool and interesting, even the ones with tiny roles.
Also, this is The Office of Pretty People. I think it's a requirement to be hired.
Sidenote: I kept getting thrown because I'm used to Hotaru as a boy's name, and have seen Hikari/Hikaru a lot as a name, too. Therefore, I keep forgetting which is her name, and that the title doesn'r refer to both their names. (Well, I only had the problem in the first ep, but...)
