Timing for Best Kdramas This Season

Did anyone notice how all of the most top-rated currently-airing k-dramas are all ending within a week? The first top-rated one ends on the 17th of this month, and then there are at least 5 popular ones ending by the 23rd. Next week's gonna be a HUGE binge-watch week for me! :) Gotta get my popcorn ready now.
