Note: The Parallel World series happened in a parallel universe; the plot and settings are completely unrelated to the previous story. This Yuka is still the famous "Vase."
The Imperial Alliance of the Stars had recently made big news.
It was said that Admiral Kenji Kuba of the Alliance Army, who was about to become the next General Fleet Admiral and known for his cold, unfeeling character, actually had a perfect pheromone match with Taira Yuka, the spoiled daughter of the wealthiest family in the universe.
The Alliance didn't force arranged marriages anymore, however, with such a high compatibility—a 100% match, everyone thought that it would be a waste if the two didn't end up together.
Also, their names would always be linked in the public's mind. Mention one, and they'd inevitably think of the other, even if they didn't marry and found different partners.
