Koharu gets frustrated by Hiyori trying to help her so much as she's fishing and Koi celebrates her sixteenth birthday.
I think Koi got her eyes from her mom.
.أظن أن كُوي ورثت أعين والدتها
Koi-chan hat wohl ihre Augen von ihr.
Credo che Koi abbia preso i suoi occhi.
Acho que os olhos da Koi-chan
são parecidos com os dela.
