I was so simple yesterday. It let me remember the time I was young,
laugh so naturally and cry so causually.
I changed myself and thought could leave no marks. Nobody felt I was
in pain. Nobody could see I was bridling. I didn't look like myself already.
I wanted to give you all the happiness in my life whatever I could.
Why did you keep pretending your hardness?
