Why I choosed to watch it? First reason - Park Si Eun, I really like her in Stayc and when I heard she was also an actress I just needed to check it out - and yes she was amazing.
Second reason - it is short, 4 episodes for 0,5 hour - yes, binge-watching worthy.
But it is not a happy, smiley show, there are meaningful and sad topics but definitely something worth watching.
