Bukti Satu Affair: Adakah Mengirim Surat Sesuatu Yang Salah?

Many people say you would know your partner when you married them, But is it true for all partners?

Takes places in a fictional Brunei, we are taken into the world of two couples via various exchange of letters. A couple in turmoil while another is in need of a talk. But the thing is no one is speaking to each other. Not couple A and not couple B. However they are speaking to the other. Seems sus. Yeah it is suspicious. And definitely an affair. Or is it?
