A million thoughts flashed through Bruno's mind in the span of a mere five seconds. Everything from the effects this offer of betrothal would have on the impact of his family, his daughter's wellbeing, and the greater implications it could have on the world and the timeline at large.
The Kaiser was trying to tie Bruno to his own family in perpetuity. As even in this era, family came first, and thus was a means to secure allegiance from powerful and talented figures. It was a bold move, especially since Bruno was of far more humble origins.
As for the boy in question who was to be his future son-in-law. Bruno's opinion of him was quite stellar. In his past life, he had forsaken his family ties after the Kaiser was deposed to marry a woman of far lesser standing, because the Kaiser did not give his blessing due to the nature of her heritage.
