One of the wisest things I have done so far is owning you.
最对的,我用最明智的wisest去诠释。
不过我觉得“拥有你”,这个逻辑上不太对,因为每个人都是独立的个体,即使结婚了,也还有隐私,不是另一个人的附属品。你可以说“爱你”。
One of the wisest things I have done so far is loving you.
The thing that I ever did right is having you,
the only correct thing I used to do is falling love with you !
