First story it's so sad, Yuma and hirono were in love with each other and hirono's younger brother was in heat and Yuma entered and he couldn't control himself and soema got pregnant, so hiromo was sad but he accepted their relationship and he disappeared... Then he came back because his brother died and found Yuma and he gave him some letters that soema wanted to send... SO SAAAAAAD
