Leo is way out of line and very creepy about Yi-Gangs Brother, like wtf what do you mean he could have his own Brother so you should get another Person? These are human you are talking about not some objects. 

He deserves that punch and should stop talking about the dead

So the plot of season 2 was ra**, more ra** and a little bit of ra** and attempted suicide.
oh and of course that they realize they "love" each other.... I don't know I am pretty sure the author could have shortened the ra** plot and focus on the character development a little bit more
