It's an adaptation of some big-boobed web illustrations, but it's also quite good and much less sleazy than I'd expected. The episodes show nothing naughty. Our heroine, Douki-chan, is an office lady who's in love with her colleague (Douki-kun) but has no idea how to snaffle him. Her plan in ep.1, for instance, is to ensure that they're "accidentally" booked into the same hotel room on a business trip and then wait for him to take indecent advantage. (He doesn't.) She's very relatable and a total loser, but you'll be cheering for her anyway. As well as cringing a bit, sometimes.
(No one in this show is named, by the way. "Douki" just means "colleague", "contemporary", etc.)
Rivals appear, always with huge boobs. There's a shameless office junior (Kouhai-chan) whose banter is either heavy flirting or offering herself on a plate. There's also a client (Senpai-san) who has history with Douki-kun and stayed in his room the last time she was in town.
It's quite fun. Douki-chan has some great facial expressions, e.g. her horror in ep10 at seeing Kouhai-chan at the pool in a bikini. I laughed. The show can also, though, be a bit of a slog to get through, because Douki-chan's efforts always fail and she's perpetually doomed to get hoist on her own petard. She scores little victories, yes, but is pretty much guaranteed to achieve nothing conclusive. (Like, say, delivering a love confession.) Ironically, over time it becomes clear that Douki-kun fancies her and isn't interested in Kouhai-chan or Senpai-san at all, but he's as rubbish at romance as she is.
It's not as heartwarming as I'd been expecting. It's not a romance, so much as a gentle comedy based on Repeated Romance Failure. It is, though, quite nice. It stars actual adults, rather than the schoolboys and schoolgirls one expects in anime. They're professional and good at their jobs, despite being clueless about their private lives. There's a bit of light fanservice, but nothing particularly noticeable. You could do worse.
