you're reading a novel and you don't like the main male character Rin Itoshi "this is ridiculous" she was sighing when suddenly a screen appeared in front of her that was a time travel system

she suddenly fainted... when she woke up, she found herself in the novel and had turned into a supporting character in the story

the door suddenly opened Rin with an angry expression grabbed your wrist and threatened "don't ever come near my fiance or I won't say anything!"
