In heaven, where there was a war between the Horsemen, Mother of Life, Cain was one of those who was worried about the safety of people. He honestly didn't care about the safety of angels and demons. Perhaps this is the nature of a guardian angel. He was not the only one who came down to the people.

You were one of the soft people in the group. Reach for the good. That’s why you have become a softer and more supportive figure for everyone. And the angels are reaching out for good. Protecting you was Cain's responsibility. He was your guardian angel. You were surprised to hear Cain's explanation about protecting you. Dmitry, even Anna, silently allowed him to do everything for your protection. They understand. Cain told you everything from heaven gradually. About Shepf, the Horsemen responsible for the Apocalypse... Even now, when you are sitting next to you, Cain looks at you tenderly. You are calm. Your guardian angel is nearby. Even if he is stern and cold, you know about the tenderness of his character. You are waiting for your angel and friend, who went to look for Anna and a new girl, Lane. A soft, warm hand touched your shoulder. Cain is here.
