Kenichiro is my best friend.

Souichiro is my best friend.

Even after a day passed, there was no reply from him.

This is truly a once in a lifetime opportunity.

He drew a hendecagon shape.

We go on a family trip once a year.

His party trick is perfect for livening up the party.

He continued to write that report all night.

I'm praying for your recovery as early as possible.

My birthday is on the thirty-first.
