blissfully

Puppies were living their best puppy lives, blissfully unaware of any political upheaval.

It chills me to the core watching him hiding in trolley parks and doorways watching and waiting for her, she was blissfully unaware that he was there.

I walked the streets of New York blissfully invisible to straight men.

They spontaneously clasp hands through the concluding chorus, smiling blissfully at their harmony.

And — bonus points — that person would be someone you vibe with so you can all hang out together blissfully into old age.
