What are the reasons for the divorce between Song Hye Kyo Jing and Song Joong Ki?

Now it is said that the man cheated, but I don't think so. How can a celebrity divorce show that one of them is cheating? I think the most fundamental reason is that when they are together, they don't have a good understanding of their inner feelings and replace the feelings of their roles, thus creating feelings similar to love. Both sides are handsome men and beautiful women, and it is inevitable to be together.

Found inappropriate after marriage, good personality, good outlook on life, good lifestyle. These reasons are all possible, and they are not the only way to cheat. It's better to celebrate your mother's birthday than to have time to care about the reasons for her divorce. Anyway, for whatever reason, they have divorced, so we should pay less attention to other people's privacy and pay more attention to their works.
