Cloud let Aerith dress him up like a whore to rescue Tifa from being savagely savaged at the hands of Don Corneo.
Meanwhile, Aerith is going around nearly getting herself killed at every turn.
I say, Cloud considers Tifa important to him and is mostly irritated by Aerith. I don't care what the pitch memos (Ultimanias or whatever) say, the logical conclusion is that Cloud is more interested in Tifa.
