Greenfingers no Hakoniwa

Asahi is a university student who is introduced to a new part-time job when a record store closes. The idea is to help a "slightly unusual botanist" who lives in a large mansion in the mountains behind the university. However, on his way to the mansion, he somehow gets lost in the mountains on a single road. In fact, Asahi had a strange experience in his childhood as well... Unseen kindness intersects with people's hopes and desires. The story of an invisible botanist and a part-time university student, and the strange plants that surround them, begins!
