It take me 0.7 eth for the transaction.Is it reasonable?
I don't think there's a way to take it back, sorry to burst the bubble for you.
You should have check the fees first before you make any transactions. And I'm just wondering why you don't know that fees now are very high and not reasonable. You should at least wait first till everything settles down. In any case though, and hopefully, you learn your hard and very expensive lessons for doing any eth transaction.
