I appreciate series like this and Lovely Writer that take a look at the ugliness that goes on behind filming dramas and what the stars go through. I like that this one has both BL and non BL storylines. Oftentimes there is a lot of jealousy that goes on behind the scenes as well as encouragement that we don't see on the outside; and unfortunately sometimes fans can get a little obsessive and take things too far and stars end up getting hurt. We're also given a taste of how actors can be mistreated or favored by their company that they work for.
*(update) that ending left this wide open for a season 2! Love the twist of ep12
