Yasuo is my best friend.

His spine is straight, and he has good posture.

He was granted a driving license.

The cause of his lateness was a train delay.

It is important to know oneself.

It is said that people born in the year of the 'Ko' (the sixth of the ten Heavenly Stems) have a special destiny.

He said his name is Kano.

It is important to believe in one's own abilities and act.

He solved the problem by himself.

Grr, you're late again!
