Arata, once and for all, tries to make the dense-as-can-be Kazuomi realize what he has in his hands.
I ended up wasting
almost the whole day!
.أضعت اليوم كلّه تقريبًا في نهاية الأمر
Nun hab ich fast den
kompletten Tag verschwendet!
J’ai gaspillé une journée entière
de mes précieuses vacances.
Alla fine mi sono rovinato la giornata.
Eu acabei gastando 
praticamente o dia todo!
Я почти весь день потратил!
