I'm not sure about a light novel exactly named 'I am my wife', but some popular light novels with unique concepts are 'Sword Art Online' and 'Re:Zero − Starting Life in Another World'. They have interesting storylines and character developments that might appeal to you if you like the idea of something out - of - the - ordinary like the title implies.
Well, light novels cover a wide range of genres. If 'I am my wife' has some sort of identity - switching or role - playing aspect in it, then 'KonoSuba' could be of interest. It's a comedic light novel with a group of misfit characters in a fantasy world. The humor and the unique character interactions might be somewhat related to the idea in 'I am my wife' if it has an element of the unexpected or different - than - normal relationships.
One could be 'My Husband is a Time Traveler'. It has a unique plot concept like 'I am my wife web novel' where the relationship dynamics are not ordinary. Another might be 'Reincarnated as My Own Sibling' which also plays with strange identity concepts in a fictional world.
I'm not sure about specific websites to read it. You could try searching on official e - book platforms like Amazon Kindle or Kobo. Sometimes, some light novel translation communities might also have it, but make sure it's legal and authorized.
Well, 'Ascendance of a Bookworm' has some similarities. The main character in that light novel has to build her own 'stardom' in a sense within the world of books and knowledge, which is different from but related to the journey of the character in 'I am a Superstar'. Also, 'KonoSuba' has a protagonist who becomes well - known in his own strange way in a fantasy world, much like how the character in 'I am a Superstar' might gain fame in their respective setting.
One similar light novel could be 'Sword Art Online'. It also has a unique world - building and engaging characters. Another one is 'Overlord', which shares the theme of a powerful protagonist in a different kind of world.
One similar light novel is 'Battle Through the Heavens'. The story follows the main character's path of self - improvement and achieving a high - level status, much like the concept in 'I am supreme light novel'. And 'Desolate Era' also has a story that involves the main character's rise to power and supremacy.
Well, 'Baccano!' could be a similar choice. It has elements of mystery, action, and a unique set of characters just like 'I am a killer light novel'. The story is told in a non - linear way which makes it really interesting. Another one is 'The Melancholy of Haruhi Suzumiya'. Although it's more on the slice - of - life side, it has some elements of mystery and the characters are really well - developed, much like in 'I am a killer light novel'.
One similar light novel could be 'Overlord'. It also features a powerful and somewhat 'evil' or at least self - interested main character in a fantasy world with elements of power, conquest, and unique character interactions. Another might be 'Re:Zero − Starting Life in Another World' which has complex characters and a dark undertone in parts, much like 'I am an evil god light novel'.
There's 'The Rising of the Shield Hero'. It has a great story about a hero who is wrongly accused and has to fight against all odds. It has elements of character growth and adventure. 'Log Horizon' is also good. It focuses on a group of players trapped in a game world and how they adapt and change it, which may be somewhat related to the appeal of 'I am trash light novel' in terms of its own world - building.
One similar light novel could be 'Re:Zero − Starting Life in Another World'. It also has a main character who initially seems out of place and has to struggle in a new and often unforgiving world.
I'm not familiar enough with 'I an my own wife light novel' to give an exact similar one. But novels like 'The Alchemist' are about self - discovery which could have some similarities in terms of the exploration of one's own self.
