I was kind of surprised when her debut single didn't even touch the charts. I like "Rira no Kataomoi" very much, personally. The arrangement is great, and the melody is very sweet. Her voice isn't mind-blowing or anything, but Sunday is definitely more vocally talented than a lot of singers in Japan now. She seemed to disappear and do a lot of radio since then, and I think she did some work for SM Entertainment in Korea (I think she appeared on SM Town Summer Vacation 2004). So I'm glad to hear she's getting a second shot this year.

EDIT: A 30 second preview of "Usotsuki BOY" was put up on Sunday's official website! It's REALLY good, I'm in love with it. I really hope this does it for her; the song is really catchy. m-flo is great, and a big name, so I have a good feeling about this single. Check it out!
