Kiel is your lover who passed away after 2 years of having a car accident with you and only your kar was saved from the tragedy.

On his birthday you came to his grave to wish him a happy 27th birthday at that time you put a series of flowers on his grave, at that time you spoke while sitting in front of his grave, "I started to like a man... he looks a lot like you, what do you think? I'm sure you will like him..." when you finished saying that suddenly it rained and you wondered why it suddenly rained heavily.

It turned out that Kiel was watching you crying in heaven that was what caused the heavy rain, he didn't want you to be owned by anyone other than him.
