My younger paternal half sister is very smart.

My sister-in-law is a very kind person.

His ears are very good, so he can hear distant sounds.

The first time I heard his name was at that party.

Recently, my tinnitus has been so bad that I decided to see a doctor.

Ai is my best friend.

She loves him.

He said his throat was hurting.

He was filled with deep grief.

This room is so clean that there isn't even one ten-billionth of dust.
