“Mr. Pei, is there anything that you’re dissatisfied with Mrs. Pei about?” a reporter asks.

Mr. Pei’s dark eyes narrows. ‘The only thing I’m not satisfied with…’

Mr. Pei answers brazenly, “Lasting for only five minutes after charging for two hours.”

Mrs. Pei’s cheeks instantly turn red and she curses inwardly, ‘This darn perv!’

The reporter asks again, “What about you, Mrs. Pei?”
