You need to watch "No Gain no love" first because this is a fun 2 episode spin off from the second leads. The girl is a writer of hot romances and ends up in her own story knowing what will happen but unable to change it. Again it is pure entertainment but fun and only 2 episodes. Not a lot moe to say but it looks like they had fun shooting this and it is worth staying around for the final clip after the credits (not that it adds anything to the story). I find these extra short stories fun (Mr Queen had one as well) but of course it is a question of taste so again you don't need to miss out on something else to watch this.
