Third force is Nishi. They are getting divorced because of Nishi. What I am guessing is maybe Nishi threatens them that if they donโt get divorced, she will cause harm to Naren and since she has already tried to kill Naren before, they will get scared... and they decide itโs best to part ways ๐คท๐ปโโ๏ธ
Itโs beyond stupid whatever the reason is for divorce.
And they have just signed the divorce papers, the divorce hasnโt been finalized yet.
