Affair
Infidelity
noun, verbal noun, な adjective
You are floating above everything, at least that's how your spirit feels. You're having an affair, and feel like nothing will catch you but... wait, what's that? Is that your wife? Oh no... not floating anymore, you're not.
This kanji uses the kun'yomi read for the first kanji, and the on'yomi reading for the second. You've learned them both already, so you should be able to read this too.

「彼は浮気をして、それを携帯電話を持っていないあなたのせいにしたってこと？」「要約するとそんなところね。」
"So he had an affair and then blamed it on you for not having a cellphone?" "That about sums it up."
