Is There Any Kind of Chronicle from 5 or 6 Years Ago?

The heroine is reborn. In the last life, she worked hard with the scumbag and died miserably. In this life, she starts a new life away from the scumbag. The heroine took part in the first college entrance examination. The first chapter tells the story of the heroine hiding in the bath of the hero (scientific researcher) in order to avoid making the same mistake again.
