BUT "you" here is second person plural - voi, and "frumoÅŸi foc" is an idiom for very cute, "as cute as a button" or "as cute as pie" are the closest idioms I could think of.
I guess it's the kind of situation when you see two people together and they look very good together, a pair looking very cute.
Aye, I understand! We have a very similar expression, but it's very dialectal and not used in standard Italian. That would sound like "Un bacio! Siete belli affoho!" (where "affoho" comes from "a" and "fuoco" ).
Anyway, I always let natives translate this sort of texts, those with idioms, because they know better what's still used. In Romanian we use this fire idiom. ^_^
Alex correct is: "să mă ajuți". "îmi" is the personal pronoun in dativ. "mă" is in accusativ, which is exactly the case you have to use here. The action (of helping) benefits you. It is like in English "I help - you help me".
