Someone know the name of a BL that the story is about a guy that has holy powers (or something like this), he dies after years of being marry to a tyrant, but then is sent back to the past by a goddess that gives him a second chance. He is a kid again and promises himself that he will never do the things that led him to that previous fate. Then he meets a little boy and helps him, so the little boy came back to visit several times and they get to be great friends. Later of course he discovers that the boy is the tyrant and is in love with him and stories show how they get together. There is fantasy about all of this, like the tyrant is of another kind of race, not human (although identical to one), it’s a race that is very strong and doesn’t knows how to show emotions very well, uses some common words in different ways (which lead to a lot of misunderstandings in previous life). I really don’t recall the name…
