Actress Goo Hye Sun and actor Ahn Jae Hyun's past marriage is again in the limelight after a resurfaced "marriage rulebook" created renewed fiery debate among netizens.

The renewed interest comes on the heels of Goo's recent Instagram rant belittling Ahn for joking about their divorce on TV shows.

Most expected that she was "triggered" by public references to his romantic exploits.

As the controversy brewed, photos of handwritten rules the pair reportedly set for each other during their marriage began circulating online.

While Goo's list contained no entries, Ahn's list was extensive, detailing expectations for his behavior.

Points for Ahn Jae Hyun to Keep in Mind

• If you're drinking outside, drink only until 11 p.m.
• Don't drink to the point of losing consciousness (do it moderately).
• Don't be stubborn.
• Don't cause harm to others.
• Put away your clothes when you take them off.
• After eating, clean up your food and dishes (don't pile them in the sink).
• Put laundry in the laundry room.
• Even if you're feeling good because you're drunk, don't yell, slap, or use other forms of violence.
• Come home by midnight (except if you're filming).
• Clean up the cat litter box once every seven days.
• Be careful of what you say (especially what you say about others).
• Organize your shoes.
• Regardless of how good you feel because you are drunk, don't shout, hit, or resort to other violence.
• Come home at midnight (unless you're shooting).
• Clean the cat litter box every seven days.
• Watch what you say (what you say about others).
• Put your shoes in order.

The list was first posted by Goo on social media in the midst of a highly publicized fight in their marriage.

Internet comments were divided, with some describing the rules as "obvious" and others saying they indicated greater problems in the marriage.

Here are some of the reactions from Korean netizens on Instiz:

"But isn't that kind of thing just obvious...? Are those really things that need to be made into rules?"

"This is really..."

"Honestly, if it were like that, I can see why they got divorced. Some rules are necessary, but you have to adjust to each other — not start off with 'You can't do this, you can't do that..."

"Visually, it is tiring to see one side with nothing and the other side full, but if you look at the contents, they're all just basic things... If those rules were written down because they weren't being followed in the first place, then in this part, I can understand Goo Hye Sun's side."

"If those were mutual rules, they'd be understandable, but the problem is that they only applied to one person... Just looking at that and the past controversies, you can kind of imagine what their marriage was like."
