Couples are unmarried but fade to black after developing feelings for each other, towards end of book. Mild language, themes of death.
My fairytale retellings are PG13 with very light swearing and mild fantasy violence (no gore/graphic scenes). Light references to sexual activity, but all activity is closed-door/off-page.
