It is an advertisment - well really fun one, it really felt more as a drama. Episodes are short and not many - also remember to check 7 first kisses endings!
And what the amazing cast we have here - my favourite: Ok Taec Yeon and Lee Jong Suk (I know them from other dramas) and Ji Chang Wook (I still need to watch something with him).
Every episode is different story, so it is really a fun watch, cause stories are totally different - my favourite was with Ji Chang Wook.
It is really worth checking if you like any of this actors or just want to watch something different.
5/10 - only because I could not rate advertisment higher, it felt wrong to me.
