What is とは in English?


I read a manga and there was this sentence:

> 巨人とは片想いのままだなクソメガネ

Some people have been saying that because the speaker says toha there is a
love that is implied to be mutual and he might be referring to himself, I
don't see why. Can anyone explain?




  * This と is "(together) with" as in 彼女 **と** 話す ("to talk with her"), 彼 **と** 知り合いになる ("to become acquainted with him").
  * This は is a familiar topic marker. You probably know は can be combined with other particles to topicalize it. This type of は does not have a good English equivalent, but pulling out the topicalized part to the beginning of the sentence has a similar effect. For example, この建物 **には** レストランがある ("In this building, there is a restaurant"), 明日 **からは** 試験がある ("From tomorrow, we have exams"), 東京 **へは** どう行きますか ("To Tokyo, how do we go?").

Thus, this Aとは roughly means "With A, ..." or "Between you and A, ...". It's
marked as the topic of the sentence. A literal translation would be as
follows:

> 巨人 **とは** 片想いのままだなクソメガネ
>
> **With** the giant, it's still a one-sided love, クソメガネ!  
>  Between you and the giant, you still have a crush, クソメガネ!
