Since this word consists of a kanji with hiragana attached, you can bet that it will use the kun'yomi reading. You didn't learn that reading with this kanji, so here's a mnemonic to help you:
Who's that you're trying to cover up? It's your fool (ふ) brother. He keeps doing embarrassing things and trying to get you in trouble. So you're trying to hide him with your jacket. Well we see him, we know he's a fool, so you can stop now.
Why would I cover up my younger brother being a criminal?
