It sort of feels like the mangaka is shipping them all together. We know Obi likes both Zen and Shirayuki equally. They also feel a strong bond with him. They both also almost seem to be flirting with him at times.
I find it cute.
For me I still ship Zen & Shirayuki together. Obi, like Kiki and Mitsuhide, is more suited to be a trusted ally that backs both of them up. That makes the whole manga very beautiful.
I don't want a cliched love tryst in this kind of uplifting, eh... overall heart-warming story (for lack of a better word). I feel the immense chemistry between Zen and Shirayuki, and I don't wanna see it broken by some love triangle plot.
Though I do find the moments they flirt with each other very cute!!! XD
I'm sorry. . . I have this kind of thought : I prefer Shirayuki to be with Obi. I'm sorry, I know that the main characters are Zen and Shirayuki, but... Sometimes I think Obi x Shirayuki pair is great either. （/TДT)/ I'm sorry.
Btw, if we're talking bout chara, not pair, I really like Mitsuhide. That's his name, rite?
