The World cup certainly had an impact.
The ratings for THREE BOLD SIBLINGS were disappointing. In all honesty this weekend’s episodes were comparatively dull.
PLEASE SEND A FANLETTER should also have done better but I understand that it did not get much publicity as far as regular broadcast shows go because it was only four episodes in total length.
My hypothesis on REBORN RICH is that having three straight episodes was a marketing strategy that worked well given that it also served up Chaebol revenge, reincarnation, etc.
