I can't remember the ending much but as i remember the ML has only ten tears to live or something i consider it a happy ending cuz they didn't show us that he died the just show us at the end that he lived with the FL happily for the rest of his life.

But as a remember there wasn't much romance
cuz im tired of RJL sad endings
