Definitely. I think Soubi is genuinely trying to form a bond with Ritsuka (because he's been told to), but he doesn't know how to do so -- all his life, people have dealt with him either by manipulation (Ritsu took his ears, led him to think he'd choose him, then handed him off to someone else) or by direct order (teachers, Seimei). Both involved the constant threat of punishment. Since Ritsuka is a Sacrifice (i.e. practically a deity) as well as the person he's been commanded to "love," Soubi isn't in a position to give him orders...

All the "love" he's ever received turned out to be manipulation, and then there's the fact that partnering Ritsuka is itself part of an order he's been given, which quite likely means "to be accomplished by any means necessary, and without regard for the consequences to either you or the target". So faced with an order to "love" (and protect/bond with as Fighter) an unknown person, he goes with what he knows of love, but he goes at it in the same way he'd approach any other order, i.e. from every angle and with no holds barred.

I giggled when you said "what KY will do".

Trust me, I did that on purpose. That was how I remembered her name back when I first entered fandom! (I kept mixing it up and muttering, "Yun Kouga? Kun Youga?" and then I realised: slash needs lube, and there is should be slash in this series, so it must be Kun Youga, i.e. KY! And I had no more trouble remembering.) :D
