Title of romance novel

The male protagonist was the main character of a game. The content of the game was to fall in love with the male protagonist. As long as the male protagonist said the words "I love you," the game would end. The female protagonist seemed to have taken it from a friend to play with. It happened to be the millennium, and the male protagonist came from the game to the real world (the male protagonist called himself the Millennium Bug). Later, the male protagonist met the creator of the game.
The creator tried every means to destroy the relationship between the male and female protagonists and even changed the game…I forgot about the rest.
The male and female leads were married, but when they got married, the male lead disappeared because he said the words 'I love you'... Who knows? Tell me!
