I just fell in love with this anime.
Yes, it is really creepy regarding some things, but once you get used to it, the bond over drool, you'll be able to appreciate the beauty about each of their actions.
Even if it's just 13 episodes, the world they're in pulled me in so much, throughout the series I felt like I was a part of that world too. I could keep on watching more episodes on this forever. That beautiful, aesthetic animation, along with the blissful sounds in each scene really got to me.
The scenery, the parks, the evening vibe, I loved it. And even the school environment really got me nostalgic about my own school days. I also commend how the creators truly captured the emotional feelings of Tsubaki-kun especially ( or boys at that age ) when going through that age phase and whilst in a relationship.
I think this is a really good anime, but it might not be for everyone.
There's certainly a lot of illogical stuff too, but it works for me at least.
