Observation diary

Crown prince Cecil was so brilliant that everything in life was easy to the point of boring him, then one day, his fiancée Bertia suddenly said "Prince Cecil, I am a villainess!" Claiming that this world is the same as that of an "otome game" from her past life and that she is playing the role of the "villainess" in it, she aims to play her part well and have their engagement annulled. With that goal in mind, she sets about causing turmoil in Cecil's daily life.

Following her marriage to Cecil, Bertia accepts a request from her new friend, Princess Lisolna Umyurbe, to help organize her own wedding to the prince of a neighbouring country. However, when Bertia begins to notice that something seems oddly familiar about her new friend and her upcoming marriage, Prince Cecil's suspicions are raised. NOTE: This is a direct sequel to An Observation Record of my Fiancée - A Self-Proclaimed Villainess.
