Could you hear the background music of my blog? It's a Japanese song, titled Tobira O Akete, meaning Open the Door. The song is taken from the anime Card Captor Sakura, a story about a girl's (Sakura) magical journey to become a Card Captor (whose duty is catching and keeping magical cards once owned by Master Clow, hence the name Clow cards) after she accidentally released the Clow cards.
