REGAIN OR RETAIN?

I knew I had the power to REGAIN OR RETAIN ..  All I have is my last card that you even don't remember..
You may not even remember the day you came in voluntarily to my room.

you might not even remember the place.. it's all in my card..I can spell the day time and place..

ask me not.. suffering to be shared.. let's share
