Ten 25-30min episodes. Some of my thoughts below. I also recommend reading the review by Virgievirgie, which sums things up well: https://mydramalist.com/profile/voicelesslove/review/330409

I will add:
I thoroughly enjoyed this. There are some moments where the manga-style humor and situations made me feel secondhand embarrassment, but it was still funny.

All of the character's are likeable and well acted. The male lead really grew on me. The female lead was written differently than many Jrom-coms and I loved it!; she's a little goofy because she's so zealous about her work but she's not ditzy or annoying, she's a bit naive but not dumb, she's not great at reading social cues but she can be empathetic, and while she has moments of shyness, she is also an engaged participant in physical intimacy and even instigates some things herself.

There is a lot of very well done, hot eroticism in the first 2/3rds, and then that fades a bit as things become more emotional in the last 1/3rd.

I expect that I will rewatch this.
