A Summer Vacation Friend - S1.E5

Summer break is quickly approaching, and Rin becomes saddened by the fact that she won't be able to see Aoki. Aoki tells her that he will still be at school to monitor the pool. Rin spends her summer with Kuro and Mimi, but at one point she is alone due to Kuro and Mimi's family-related absences. Rin remembers what Aoki says and goes to the school where she finds Aoki talking with Hoin. Aoki spots Rin and chases her to the pool where Rin pushes him in. She hugs him and they watch the fireworks.
