Toaru Kagaku no Railgun SS - Volume 2, Chapter 1

After Gu Jinghe passed through the book, she became a cold and ruthless overlord. The system asked her to abuse her heart and body against the poor heroine, and the world was broken.
The heroine is both beautiful and miserable, Gu Jinghe couldn’t bear it, and decided to put on another vest to secretly compensate her.
She seamlessly switches between old and new identities, and lives like a genius every day.
When she was the overlord, she looked cold and stern, with a mocking smile on her lips, and her fingers raised the heroine’s chin: “Ji Yunyan, the fate of the Ji family is in my hands, you’d better be obedient.”
In her new identity, she smiled brightly, and her voice was sweet and soft: “Yanyan, can I go to your house to do my homework?”
Probably because of her superb acting skills, the heroine treats her with a cold face as the domineering boss, and smiles like a flower at her new identity.
Until one day, when Gu Jinghe routinely confronted Ji Yunyan as the boss, Tian Liang Ji Po, Ji Yunyan suddenly called out her vest name to her.
Gu Jinghe agreed…
Gu Jinghe: Why don’t you listen to my explanation?
Ji Yunyan: (smiling) Make it up, keep making it up.
