Kyoichi is my best friend.

A footrace was held at the school's sports festival.

I will go to watch the boat race today.

He learned a big lesson from that failure.

He taught me an important lesson.

This car is our family's joint possession.

His belief is firm.

His belief was firm, and no one could shake it.
