The story starts with them being children the beginning is extremely cute as we get a good idea of how their bond formed. one of them goes to live with his mother and leaves without giving any warning they find each other again after 10 years and slowly a bit more of their past is being uncovered some of the same memories are replayed but give more insight of what happened in the moment every time it gets replayed making the plot of the story suspenseful every time something new is reveled. the overall feeling i get when watching the series is warm and bubbly with a good amount of suspense sprinkled in there i totally recommend watching it .
