He successfully completed his first year at university.

This is my first experience, and I'm very excited.

He made his debut on stage yesterday.

I don't know what to do on a first date.

I can't forget my first kiss with him.

He made his debut in a professional baseball game yesterday.

The first frost of the year came early, didn't it?

At our first meeting, he behaved very kindly.

He was looking far away.

His appearance is very youthful.
