Yesterday's friend left quietly, just like this without a sound what song is this?

Hello, the song you're asking about is this one, I hope it works for you

Ko Sung-mei - Walking in Style

Yesterday's friend left quietly

Leaving you so silently

It seems as if I can see in your eyes

Feeling infinite sorrow

It seems as if the night fog is covering your heart

Maybe you never want to tell me

I don't want to ask why.

I don't want to ask you why

Summer winds have blown far away

Blown away without a trace

So I'll forget about you last night

Don't say that love is your first name and your last name

You don't want to get close to me except for your feelings

Broken heart is hard to fill

Yesterday's drunken love

So I'll forget your back

Yesterday's friend left quietly

Leaving you like this

It's as if in your eyes

I feel infinite sorrow

It's as if the night fog is covering your heart

Maybe you never want to tell me

I don't want to ask you again

Summer winds have blown far away

Blown away without a trace

So I'll forget about you last night

Don't say that love is your first name and last name

You don't want to get close to me except for your feelings

Broken heart can't be filled in

Yesterday's intoxicating love

So I'll forget about your back

I'll forget about you.

So I'll forget your back
