why are you guys making it so complicated!?
Cloud likes aerith and Tifa BUT! read first before you correct me,Cloud only sees Aerith as a close friend...he feels guilty for her death....Cloud loves Tifa (i mean,she is his childhood friend/crush rite?)...he distanced himself from Tifa,Marlene and Denzel because of the disease. He felt that if he couldnt even protect himself,how can he protect them? he doesnt want what happened to Aerith and Zack to happen to Tifa,Marlene and Denzel.....
Aerith liked cloud because she thought he was more like Zack....she only likes him(Cloud) as a close friend...
AND...(yup..theres more),I think Tifa held back for awhile because she didnt want to ruin their friendship....
Oh yeah,another thing, "has feelings for.........." does mean they like that person more than a friend....
