Guardian angel....on 21st March

Today someone told me that she/he wants to be my guardian angel.... to be with me when i'm lonely, to be with me when i'm not happy, to be with me when i feel scared, to be with me when i'm being bully and will protect me. who told me this??? 不能说的秘密. At that moment I feel touch... and then, I've realize that God have sent me 2 angels for years edy... Guess who is my angel???
