Socially awkward Mishikima is a plant nerd. So he joins a club where he can research plants. That's where he meets Mori-san. Our main heroine Mori-san who is socially awkward dryad and quiet shy person while keeping her poker face. Every time she gets nervous transforms into a tree. And that's quite amusing to see.
I recommend this manga to those who are looking for short fluffy rom-com manga and Ki ni Naru Mori-san is just for you.
The story is good, the art is fantastic, and the character design is good. There's also characters development and fluffy romance to enjoy.
