As mentioned in the MEDIA TAB of YUI-net, YUI (and her team) guested in Hisashi Kondo's (which is his music director/arranger/etc.) radio show Sata-Young. The episode was about trouble consultations and callers will ask for advise/tips/consultations for their troubles/problems.
Here are several posts about it in
