2021년 1월 18일 방영
Renge, Hotaru, and the Koshigaya siblings help Kazuho to plant seedlings in the Miyauchi's garden. They build a greenhouse for the seedlings after it starts raining and Renge worries they will get cold. That Sunday Konomi introduces Akane -who at first thinks Hotaru is older- to the other girls to help her with her anxiety. Later that week Hotaru, who after all is a 5th grader, is embarrassed when Konomi sees her acting childlike. (Source: Wikipedia)
