You are the Grudge Bookkeeper
A cold brain who designs the accounting of revenge from the shadows.
What kind of villain
You handle grudges as data, not emotion. Backstage and quiet, you precisely design who to bring down, when, and how. Explosive vengeance isn't your taste — you'd rather settle the account down to the last line before the target even notices. Yet because the board stays 'those who dismissed me' rather than 'the world,' you are frighteningly competent but, in the end, a personal avenger.
In everyday life
You don't fight back on a wave of heated emotion. When something unjust happens, instead of flaring up you quietly gather the facts. You save the messages, check the dates, file it all calmly away. Then, at the one moment that truly matters, you lay it out just once. Even as the situation resolves itself in an instant, you simply accept it without a flicker.

Advice
Turning hurt and injustice into calm logic and evidence, rather than an emotional outpouring, is a remarkable wisdom and skill. But if you treat every relationship as something to prepare a case for, even those closest to you may start to find you a little hard to approach. Try gently separating the people you record from the people you simply trust. Having someone you can open your heart to with no defences at all will become the warmest asset in your life.
