My favorite episode was the 9th, the segment of the ex-convict and the reason behind Yuki's early departure from the bar she's working in. Found it emotionally moving, switching from sakura petals to violets, welcoming change and new beginnings.
This drama keeps their viewers on their toes and guess who's to trust and not. Everyone is so suspicious af and the mystery thickens. This may be a tale of an agency taking down a top agent or someone betraying it as a whole.
