One popular 'secret identity slice of life light novel' is 'My Youth Romantic Comedy Is Wrong, As I Expected'. The main character Hachiman has a sort of secret identity in the sense that his true thoughts and feelings are often hidden behind his cynical exterior. It shows his daily life in school, dealing with friends and various social situations.
Another one could be 'The Devil Is a Part - Timer!'. Satan disguises himself as a human and lives an ordinary slice - of - life in modern - day Tokyo. It's a really fun take on the secret identity concept within a slice - of - life setting, with lots of comical moments as he tries to adapt to human life while hiding his true identity.
'Kaguya - sama: Love Is War' also has elements of this. The two main characters, Kaguya and Miyuki, both have their own 'secret identities' in a way. They are both highly intelligent and prideful, and they hide their true feelings of love from each other while living their school life full of various events and interactions.
