The lyrics of this is the first time

this is

This is key, but the door is open

This is room

This is heart, but I don't want it to cry any more

This is dog

This is you

She is my best friend

You and her

It's just a hug

I don't think we'll be together until we get old

Even if it's a kiss

It's just politeness. It's not bothering

I decline

First happy then lonely

Don't tell me it's your vulnerability

What is love

You get your excuse back

I accept

You want her and you want me

Like the love of every greedy person

There is always more loneliness to get rid of

You can leave now.

You and her

It's just a hug

I don't think we'll be together until we get old

Even if it's a kiss

It's just politeness. It's not bothering

I decline

First happy then lonely

Don't tell me it's your vulnerability

What is love

You get your excuse back

I accept

You want her and you want me

Like the love of every greedy person

There is always more loneliness to get rid of

You can leave now.

This is key, but the door is open

This is room

This is heart, but I don't want it to cry any more
