@Aditi Johri I think the author may had a special hatred towards the girl name " Annette " in real life. Maybe that's why he wrote this manga to make the girl Annette the fl so he can make her miserable and never let happiness even touch her. From what I'm seeing so far now I can only get this conclusion that he might have a girl whose name maybe was Annette in his real life bcz from the very start the author didn't even let the fl be happy for even more than a second so yeah maybe the Annette name was his crush who whose another men over him that's why he is taking his anger on manga.
