Villain: Transmigrated Into A NTR Manga As The Antagonist

Isabella was just about to watch the private video collection of Alex that she had paid a fortune for when the door to her room burst open to reveal her older half brother Angel. Isabella had already loaded the video onto her computer screen, and it was playing in the background while she stared at her brother in horror.

The handsome and vicious young drug prince stared at his little sister with a look of disgust on his face as he saw what she was watching, and immediately demanded she hand over all of her devices that could connect to the internet. There was no fury in his voice, yet Isabella knew by experience that the man was absolutely enraged that she would watch such a thing.

"Isabella… Hand me all of your electronics… now…."
