Three examples of love for each character

I can't go through every character but I can make some general statements. Duke Orsino loves from afar. His love is idealized rather than substantial. There is familial love that Viola feels for her brother. She laments that her brother Sebastian is lost at sea and she mourns him for seven years. There is the love that a servant feels for the master (Antonio and Sebastian). There is finally romantic love that we see between Orsino and Viola.
