generally speaking, office romance drags on productivity and encourages nepotism. If two people finally break up, it can be another source of office politics.
Most firms have a policy of discouragement, if not outright ban.
To be frank, if I were the boss of two people in serious love, I will persuade one to resign or assign one to another office which has no direct conflict of interests with the current department.
Office romance is a dangerous thing for your firm.
