It doesn't make sense that he gets to sacrifice his love for her to exist and he also helps her achieve her love. They never explained how the parents got together, them being his ex and his bestfriend and the ML broke up with her. The logic doesn't make sense and how does a tortoise travel that far. The idea that he had to sacrifice his true love for another stranger he never met never made sense. Looked like the writers forced the love angle of the parents. Nahh this movie just made me angry and sad, korean romance movies always leave me hurting. Is that a forever existing trend.
