No wonder he is so tired, he has been working all day.

No wonder, I understood why he is so tired.

He is working in a large oil field in Saudi Arabia.

Kaede is my best friend.

The maple leaves are dancing in the autumn wind.

The children were playing by beating the pellet drum.

He blames himself for anything and everything.

All ended well, so all is well that ends well.

I met him for the first time, and that was the beginning of fate.

He is my friend and at the same time, he is also my business partner.
