Transmigrating into a Book: When the Transmigrated Side Character Meets the Reborn Heroine

This story is a little self-indulgent. All right, it's really self-indulgent.

I'm a little lazy. All right, I'm really lazy.

So if updates are late or slow, don't blame me.

Here's the basic idea: the original work in the story is something I made up myself, so this isn't fanfiction.

It's about an icy heroine from a powerful family whose own abilities are even more formidable. After being betrayed by the person she loved most before she was reborn, she meets a transmigrated supporting heroine with a System and instantly turns into her loyal dog.
