I Plan to End This Possession

Yeon Dana had taken possession of ‘Danae Windsor.’ The only escape route back to her world was through the Dimensional Gate.
Yet, upon the heartbreaking request of her loved ones, she made the decision not to go. She turned away from the gate, which opens only every 100 years.
Three years later. The same people who were so desperate to keep Dana revealed their true faces.
“I do not want to end the engagement. But I want to marry her, too.” Her fiancé being unashamed by marrying another girl;
“I kept you hostage just to show you that you don’t have to worry about going back.” Her younger brother’s prank making sense only now;
“Nobody made you stay here by force.” And her elder cousin’s mocking.
“The Dimensional Gate is shut down. So forget about escaping!”
Yet, Dana has knowledge that others are unaware of. She knows how to bring this possession to an end and how to return to her home planet. Although the feeling of being betrayed by loved ones was stressful for her, it did not stay long. The rage inside her is much stronger and brings her thoughts to revenge followed by escaping.
‘So those bastards played me.’
In fact, I wanted to be quiet and live a nice life.
‘You picked the wrong time to make a mess of my life.’
She makes her mind up to return to her world at the moment those bastards think that they keep her forever.
