I'm kinda surprised that someone who apparently likes the characters didn't seem to think about how they like, uh, felt.
On the other hand, it's quite believable that you neither like the characters nor are able to think about how they felt, huh?
Here's the easiest proof that it was a happy ending: because it was presented as one. It simply didn't feel bittersweet in the least. That's QED.
