Well since his wife "left" him, i guess he is free to have an office affair.
But neither seem to be series, the wife just left in order to fuck with him, but she doesn't really has a plan and will go back to him eventually, and this other woman is only saying that she is interested on him in order to avoid the drama that follows the popular guys.
But the real problem here is his friend that will try to root him with his awful hobbies, he goes to the shittiest establishments.
