Soul-Maka: possible?

I've been thinking of pairing up Maka Albarn and Soul Eater Evans of the anime entitled, Soul Eater. There are no hints of any romantic relationships between them, but it seems that they carry an intimate caring feeling towards each other. One of the episodes in the said anime (ep.5), Soul stated that he won't let professor Stein to lay a finger on Maka, which greatly shows that he cares for her, and vice versa. Does it sound impossible?
