I enjoyed all the series. From the first series, Love Set which is portrays Persona as a child (how she holds her persona till the end) until the last one, Walking At Night with more deep stories in it. We can't tell how people's life been going through (we don't know which persona they used) till they speak themselves. Eventhough its short but each series could expressed the persona itself. Well done.
It's worth to watch for me
