Bro this is disgusting. ML is married but he's cheating with FL but also won't divorce his wife and wife is also cheating with someone else on ML and FL has a boyfriend but is cheating on him with ML. This is just made to try to excuse cheating. Get a life.
Don't listen to other comments ʕ·ᴥ·ʔ People say cheating is bad. Yes. It only correct when two people falls in love. But not with the people who married just for business. In this manga, both married man and woman doesn't love each other and they have their own lover. No strings attached. Why are ya all hate them lol. Even if they love each other, in some cases love can fade away and we can fall for someone else. When you start to have feelings for someone else, you should open up to our partner and divorce. Some people can love only one person but not for others. They don't have intention to cheat but it just happens. If only you can try to understand... Love is strange.
