Koharu gets frustrated by Hiyori trying to help her so much as she's fishing and Koi celebrates her sixteenth birthday.
So she's trying extra hard
to make sure you have fun.
.لهذا فهي تحاول جاهدةً جعلكِ تستمتعين
Entsprechend legt sie sich ins Zeug,
es dir schmackhaft zu machen.
Se emociona así
porque quiere que lo disfrutes.
Elle se démène
pour que ça te plaise.
Quindi ce la mette tutta 
perché tu la trovi divertente.
Ela está se esforçando
para que você se divirta.
