He goes back to his cell happily by wishing them all success.

He went happily to bed and did not wake up.

Somewhere out in the city, happily going about his work.

A few years later they have a son and life happily goes on.

He went happily about finding out why they did not.

I can happily go a couple of days without drinking if I've got some weed.

As it happens, he went off to bed quite happily.
