Where to begin the series was perfect only problem it had was confusing ending and not confirming the season 2 even though it's been months after it aired.
Acting was good the character development was given to almost all characters introduced but it had ending moved towards to feel more of a sad but they had a twist to the end which is like what the dash is happening in the screen.
It had wibe of kdrama like mr.queen or the scarlet love so if like those wonder what will happen if it's bl here the show. Also the ending is a open door so don't watch if have anxiety problem.
