Harry didn't have much right to meddle in her private affairs. And Cleo had succumbed to him enough to not go anywhere today but to the one place. Harry should have tolerated her, but instead, he got angry.
"Do you think I am your puppet who has to follow your wishes? If you say 'A', then I will do 'A'. And if you say 'B', then I will do 'B'. You're clearly too much, Harry Miles Theodore!"
Cleo deliberately showed her arrogant attitude as not to continued to be colonized.
Harry seemed to have looked at Cleo more deeply. Knew that Cleo was not a woman he can easily subdue. And he didn't want him to look so easy to beat. Harry was no less fierce than Cleo.
"You're still my wife even if it's only a contract. Don't make me repeat what I said because I don't like it. Miles' name is also engraved on your last name when you have a status as my wife. You shouldn't be able to just go out and meet your man. I'm still your husband," Harry said stubbornly.
