Lovino loves it that Antonio is always able to be and happy and look on the positive sides of everyday life.
Because it hurts when He has to hold Antonio at night when Antonio has awaken from a nightmare and try to calm him when he screams that he killed all the Aztecs.
(Historical fact: when the Spaniards arrived in the new land and start to take over, they killed thousands of Aztec people and basically destroyed the culture and the people. So..... Plus the fact that Antonio is always positive it kinda makes you wonder..... Okay I'm going to leave before I get killed! ~Windy)
