Body swapping and kissing.
The first episode was way better than I expected. I have read the manga but I wasn’t a huge fan of it. It’s pretty much a generic school harem but with weird kissing powers (which of course is already an improvement).
This episode had a good sense of pacing and of humor. It didn’t drag or feel boring.
I also like how they did the body swapping, with the changed voices and mannerisms. Seeing Yamada in Shiraishi’s body was pretty funny. I also like how Shiraishi has quite a strong personality, more so than I remembered from the manga.
Overall, this is off to a surprisingly decent start.
