Pseudo Relationship: Part 1

They are officemates. They are not in a relationship but they have this special bond. They share their constant ramblings and understand each other well. They been on the said "relationship"  (the parang kami or hindi relationship) for almost a year. They share private messages using their personal emails, YM and even text messages. They are both married and living a happy life. But
could you just imagine that they are happier when they are together and not when they are with their original partners? The girl could not live the guy alone nor the
other way around. Nobody knew their whereabouts, they have been very secretive. They usually go out and even had sex more than once before. They get jealous at each other but could not tell it afraid that it might break the so-called relationship. They are acting like they have something but they just tell everyone they do not have. A very complicated situation. Fallen with each others trap. No holding back of feelings. Just taking the risk of being happy and merry. 

Is it love or just a normal feeling? I'm not a judge, you aren't a judge either.

Present.....  they
are very good friends but with no benefits at all. They both have a hard time letting go each other.. Pseudo relationship. The parang kami, parang hindi relationship is just so damn difficult to deal with. .....

Who are they? I am asking you too..
