Hatsukoi (First Love) Limited was an enjoyable fanservice show from 2009 from J.C. Staff (gasp, I know). If you like light romantic comedy anime that doesn’t get too serious then try this one out. It even had one character voiced by Aki Toyosaki that REALLY liked her brother. 😉
Still waiting for Kanamemo to be licensed though.
But anyway, check out the nice OP it had.
