You Know, I Want to Tell You Something is a talk song from THE iDOLM@STER MILLION LIVE!. It was sung by Haruka the Vocal idol.
You know I want to tell you something. Ritsuko is the rival of her group, Iori, Ami and Auzsa. She does everything she can to help the girls. My friend, Anna, is very shy and cute but likes me. Do you know?! She's a famous funky girl! I love her very much! And you know that. Well, that's all from me. Gotta go join 765 Pro! See you later!
