The manga and anime leave their relationship ambiguous, focusing on their professional partnership and mutual respect.
Here's why it's not explicitly stated:
* The focus is on the story: The series primarily centers around the fight against the homunculi and the larger themes of ambition, redemption, and morality.
* Complex personalities: Both characters are complex and driven individuals, making a romantic relationship a potential distraction from their overarching goals.
* Respectful dynamic: Their relationship is built on trust, loyalty, and shared dedication, making it an intensely complex and deeply satisfying dynamic without the need for romantic involvement.
However, there are some hints and fan interpretations that suggest a potential for romance:
* Close proximity: They share a strong connection and are often seen working closely together.
* Mutual respect: Both characters have a deep respect for each other's abilities and intelligence.
* Protective instincts: They fiercely protect each other and demonstrate a level of care that goes beyond the professional.
Ultimately, whether or not they go on a date is up to individual interpretation.
The beauty of the series lies in its ability to leave room for speculation and personal connection with the characters. You can choose to see their dynamic as platonic or romantic, depending on your own preferences and reading of the story.
