Tsuwabuki is an ordinary student with poor social skills until his encounter with two gardening club members, including new student Sumomo Akihime, changes everything. After being pressurized by a teacher, he reluctantly joins the club only to be accidentally transformed into a plush toy by a strange individual with dog-like ears. To regain his human form, Tsuwabuki must locate the chosen girl and gather seven stardrops, an impossible task without Sumomo's assistance. Despite her challenges, Sumomo agrees to help Tsuwabuki, unaware of the true identity of the transformed animal.
