" The main characters relationship is not specifically a love story. You can certainly take it in that direction if you wish, though. Their relationship is defined by two different axes: Affection and Affinity. Affection is how much they like each other, Affinity is how well they agree with each other on moral dilemmas. So they might hate each other, but work well. You aren't going to accidentally end up as your friend's gay lover, it'll be a conscious choice if you go for that. "
(Matt Barton and Swen Vincke video chat)
This seems like a pretty clear acknowledgment of romance.
