Maybe that time her half-deaf effected to her singing skill very much and the injury on her hand also has a bad effect to her health so she can't be well-prepared for PCDL.
But she got the balance again in the following years. That's just the past and now, all of us should give give her a break.
Even though Carols in CDL 2013-2014 is lip-synched or not, she has tried her best and CDL is over too. We needn't to discuss about this question anymore. Just waiting for the TV version or the DVD/Bluray news !
In January, the show of TV Asashi will be full released soon and the news about "Pray" will be reported soon ! Right !?
That will be the events for us to discuss !
