The lyrics include: One day, when the weather is fine (probably), ask for a song title, thank you!

When the landlord heard that sentence, it might be "it's always good weather to look up."

If so, then that song should be "the secret hidden in a smile".

This song was sung by Zhao Yonghua, which is an episode of Taiwan Province's idol drama "The Kiss of Pranks".

The lyrics are as follows:

Because the grass outside the window smells good.

Blowing my face. Oh, la, la.

Because the sky is covered with a golden sun.

Shiny oh, la, la.

Because of the message you sent me

Shocked my heart.

I'm so happy, I want it.

Sing loudly. Oh, la, la.

Like a blooming flower, it doesn't need a blueprint.

Don't dream.

It's like flowing to the sea without commitment

There is also power. Oh, la la.

As much as I love you.

Naturally, don't think about it.

Something good is bound to happen.

On the way to your place.

Oh, love is calling you face to face.

This is the secret I hide in my smile.

Do you realize that as long as we are together?

It's always fine to look up.

Oh, love makes people full of courage

It's also the secret I hide in my smile.

I signed my name in my heart, for you moved me.

I know heaven is in my heart, in my heart.

I know heaven is in my heart.

I opened my eyes to see you.

Look at how beautiful the world is.

See every white cloud and every leaf.

They are all saying I love you.
