Koharu gets frustrated by Hiyori trying to help her so much as she's fishing and Koi celebrates her sixteenth birthday.
It doesn't make any difference
if Dad is around anyway.
.وجود أبي من عدمه لا يحدث فارقاً على أي حال
Macht eh keinen Unterschied,
ob Papa da ist oder nicht.
Después de todo,
da igual si papá está o no.
Ça change rien
que papa soit là ou non !
tanto che papà ci fosse o no 
non faceva differenza.
Afinal, o papai estando
ou não presente, dá na mesma.
