I don't know the manga, but out of curiosity I managed to watch the Dorama / Live-action movie a few months ago.
There it seemed already a light-hearted comedy-shoujo series and the first episode of the anime followed in this.
I really enjoyed the first episode and I laughed at quite some scenes
Overall, I think I'm going to keep this one as it seems to serve good comedy, a warm atmosphere and the love interests began to shine through at the end of the episode and I am curious how they (staff) play it out
