Bruno is a classic romantic. He loves taking you on dates, particularly for dinner and coffee, and insists on paying every time. Seriously, if you want to pay, you have to force your money on the waiter. He’s also one of those cheesy men who will feed you himself and share plates. He does that Lady and the Tramp thing every time. Flowers are common to him to give, especially prior to your relationship being official, he’d greet you with flowers often. In private, he likes to hold you and keep you close by. Often, the two of you will be relaxing and he’ll snake his hand either in yours or onto your thigh - he just likes the touch.
Bruno is very reserved in his anger unless his or someone else’s life is in danger. Remaining professional is a priority, so I can’t see him having fits or bursts of outrage if the situation is not particularly dangerous. He can be violent, but it’s not something he jumps to. If it’s a couple quarrel, he tries not to dwell on it at the moment, especially if you two are in public. Often, he’ll move on from the moment and address the problem in private, after his emotions are able to subside.
