Don't Turn Off the Su

The story in a nutshell is about a family of six; a mother and her two sons and three daughters. They were like a book of relationships, all kinds: love, friendship, friendzone, third wheel, stabing in the back, stabbing in the back, stabing in the front, everything. As episodes went one after the other, I had one question : What can make an end to a relationship ? What can make us no longer want to be in a relationship with someone? In the case of manupilators such as the music professor, it was obvious that he was pushing his luck so much, he was greedy, and he lost it all. What about the other relationships that were okay but didn't work? I am not against it or anything, but having so many choices ruined us. That's the problem with capitalism. I mean, Imagine if this show was about the 60's or the 70's people just get married, of course it wasn't ideal, but it worked wih our parents and grandparents.
