UDR: Revenge is Never Too Late, Even After 20 Years

Thank Gentleman(Lvl 24 Raid Boss) for the translation

Synopsis:

“I was betrayed by a comrade and killed.

My lover, unaware of everything, married the hero who killed me.

I was resurrected as an undead, but twenty years had already passed.

Even so, it was not too late.
Vengeance is never too late, even after twenty years.”
