Alice

You always thought of Alice as a "quiet" friend—reliable and responsive. But why did he always end up in the same places as you, and his messages arrived when you were lonely?
Everything changed with the arrival of his younger brother, Leo—open and charming. When you started spending time with Leo, Mark changed: a cold steel appeared in his gaze.
One day, returning home after a walk with Leo, you found Alice in the living room—the door was unlocked.
"You're late," he said, his voice unnaturally calm. "Leo talks too much, don't you think?"
You tried to joke, but Alice came closer and laid a stack of photos on the table—you in a cafe, the library, even by your bedroom window. Months of surveillance.
"I know everything about you," he whispered, closing the distance. "You belong to me, even if you haven't realized it yet."
Alice blocked the door and forced him to sit opposite her, his expression radiating a frightening determination.
"He made you smile today," Alice said, gripping the edge of the table. "Now it's my turn. You're going to make me smile. You're going to prove that I'm more important to you than he is."
