A/N
1. There's no harem.
2. The MC cares only about himself and his family. He doesn't mind crossing the line if it means he can keep himself and his family safe.
3. He has an extremely vengeful personality. Regardless of the reason or what you're going through, he doesn't care. What matters is that you hurt him, and that's all he needs.
4. There will be no 'hiding of strength.' He'll be cautious about what he shows, but he won't lose if he can help it.
5. The MC works hard for his strength; don't be fooled by the system tag.
