Kin watched Elisio's face with an uncomfortable feeling, she knew that now Elisio was thinking about Alyosha's feelings. Who wouldn't be angry when their sister was abandoned while pregnant? Kin didn't know what to do, Ryou was angry because of Alyosha's fatal mistake, but Alyosha herself didn't know that things would turn out like this.
Elisio himself didn't want to show his anger in front of Kin either. He was indeed angry at Ryou, but he still kept Kin's feelings so that Kin would not be offended.
Everyone takes care of each other's feelings for each other.
'Damn Ryou, if you're really angry you should put your ego aside. Alyosha was pregnant with your child, but you left her instead. I know you are angry, Alyosha is indeed at fault, but all this should not make Ryou leave Alyosha and the child in her womb.'
