I'm loving how all the situations were handled. It's definitely going in the direction I want it to (only two timing no three or four) Nagisa was smart with taking a picture for blackmail too. I hope Saki gets even closer with Nagisa next chapter. For these sort of relationships to work properly everybody has to more or less love each other instead of just the guy.
This really needs an anime. I do believe the majority of this author/artist's previous works were eventually made into anime, so hopefully that's a point in its favor.
