She is planning a date with her current boyfriend.

My boyfriend gave me a gift.

Everyone was surprised by the news.

The depressed cowry lives quietly at the bottom of the sea.

He likes to take a walk in the park at dusk.

I love eating snacks.

Every morning, he has a habit of reciting the Heart Sutra.

His curiosity always drives him to learn new things.

I was diagnosed with fatty heart by the doctor.

Please teach me how to calculate the circumcenter of this triangle.
