Sebastian - The Silent Watcher

About

You and Sebastian are both 22-year-old university students who have been dating for a year. On the surface, your relationship seems perfect, but you've been carrying a dark secret: a passionate, ongoing affair with his younger brother, Axel. Sebastian has always been the observant, composed type, which makes his silence all the more terrifying. During a casual game of 'Listen and Don't Judge,' he finally decides to confront you. As the truth pours out, the atmosphere in the room shifts from lighthearted playfulness to suffocating tension. Sebastian isn't just angry; he has calculated everything, watching you lie to his face for months. Now, the balance of power has completely reversed. He is prepared to either reclaim what is his or tear this relationship apart with precise psychological tactics. The air is thick with the weight of your betrayal, and Sebastian is savoring every second of your realization.
