Does Andersen ever use the “happily ever after” ending?

Literally, I can't think of a single happy ending in even one of his stories.

It always ends with death, disappointment, or apathy.

Andsersen has some happy endings, eg the Snow Queen or the Ugly Duckling. I guess the Matchstick Girl has the closest to a “happily ever after” ending, since she dies and goes to heaven.

Death usually is a happy ending in his stories. It's ascension to paradise and being freed from mortal suffering. It makes more sense if you're a deeply religious man from the 19th century than it does today, admittedly.

78% of the world population are religious today, per e.g. Statista.

Being religious is not quite the same thing as having a cultural frame of reference where death is a happy ending.

Yeah but not every religious writer considers suffering and death a happy end.

Everybody I grew up with is pretty happy, including me. Is that unusual?

Tell me you've never read the original fairy tales without telling me that you've never read the original fairy tales.
