Many times, I've been thinking about this question: we love each other, but only in the network, we have never met, we don't know each other's address or phone number, or even what the other person does for a living, where they work, how old they are, and many other things we do not know.
We fall in love with just an ID, or the name that ID represents. Behind this name, what kind of person is there, we don't know. Sometimes, it even leads to farcical situations like mistaken identity dramas.
