分かるわかる

何なにを言いってるのか分わからない

nani wo i tteru no ka wakara nai

I don't understand what you're saying

それは俺おれもよく分わかってない

sore wa ore mo yoku wakatte nai!!

I don't understand that well either!!

分わかるまで何度なんども

wakaru made nando mo

Until you understand, over and over

無駄むだなことだってまだ分わからないの？

muda na koto datte mada wakara nai no?

Don't you still understand it's pointless?

私わたしにはその理由りゆうが分わかる

watashi ni wa sono riyuu ga wakaru

I understand the reason for that
