It is Qu Wanting's "In My Singing"

The lyrics are as follows:

Without a little precaution or a little concern

You just appeared in my world.

Surprise me. I cann't help myself

But you're doing this again

Disappear quietly before I know it.

There is no news from my world.

All that's left is memories

You exist in my deep mind.

In my dreams, in my heart, in my songs.

You exist in my deep mind.

In my dreams, in my heart, in my songs.

Remember when we used to

Walk side by side through the bustling alley.

Although you and I are strangers and passers-by.

But we still feel each other's.

A look, a heartbeat.

An unexpected pleasure.

It's like a dream, destiny takes a hand.

You exist in my deep mind.

In my dreams, in my heart, in my songs.

You exist in my deep mind.

In my dreams, in my heart, in my songs.

The world is so big, why do we meet?

Is it fate or providence?

You exist in my deep mind.

In my dreams, in my heart, in my songs.

You exist in my deep mind.

In my dreams, in my heart, in my songs.

You exist in my deep mind.

In my dreams, in my heart, in my songs.
