That's right, I don't know if I'm drunk.
I don't know if it's a mistake either.
When the morning comes,
I don't remember a thing.
I'm not sure if that
makes you nervous.
However, tonight.
here's something I must tell you.
'm sorry to show you
my vulnerabilities.
Don't just think I'm saying this
because I'm drunk.
When I stand in front of you
I thought I'd be ready, but I'd say
the opposite of what I want to say.
Or I would look back upon it
and regret those words.
I would confess how I feel and tell you
that I loved you from the start.
I'd say I love you like this...
this is the lyrics from the subtitle
thanks
