Flashback: It happened on the day the SNMPTN results were announced.

Carissa was sitting on her bed when a knock came at her door. She did not move right away. Something about it made her hesitate, as if her body already knew what was coming. Before she could even decide whether to stand up, the door opened on its own.

Gentara stepped inside.

The moment she saw his face, the small smile on her lips disappeared. It was like something inside her dropped. Her heart began to beat in a way that did not feel normal, and her hands turned damp where they rested on the bed.

He walked in as if he owned the space, as if her room was nothing more than another place for him to take over. There was a strange smile on his face, one that made her stomach turn. When he shut the door behind him, the sound felt louder than it should have.

Carissa stayed where she was, sitting stiffly on the bed, her body already reacting even before anything happened.

“I heard from Mom that you passed your test,” he said while walking closer. “You got in, right?”

She did not answer. Her throat felt tight, and her mind was trying to keep up with the fear building inside her.

“Why are you quiet? I asked you something, Car.”

He sat down at the edge of the bed, close enough that she could feel his presence without even looking at him. His hand reached out and brushed against her cheek.

Carissa turned her face away quickly, refusing to let him touch her. Her reaction was small, but it took effort. Slowly, she nodded, giving him the answer he wanted without speaking.

Gentara let out a rough breath. For a moment, he looked away from her, and his expression changed into something flat, something harder to read.

“So you are leaving for Jakarta,” he said.

There was disappointment in his voice, and that alone made Carissa feel something close to relief. The thought of leaving this house, of putting distance between herself and him, felt like the only good thing in her life right now. If she could go, maybe she could finally be free from the man who had made her life unbearable.

Gentara clicked his tongue and stood up. He slid his hands into his pockets and began to walk back and forth beside the bed. The room fell into silence, but it was not peaceful. It felt heavy, like something was building.

He was thinking. Carissa could see it in the way he moved. Looking for a way to stop her from leaving.

“Why do you even want to go to college?” he asked suddenly.

Carissa flinched. His voice had risen, sharper now, even though his face still looked controlled. Anyone who did not know him might think he was calm, but she knew better.

“If your reason is just to get a degree so you can work at some big company, then you should forget it,” he continued. “You already have a good life here since your mother married my father. You can just stay here with me. Even if you do nothing, I will not let you suffer. You can ask me for anything. Money, a car, whatever you want.”

His words went on and on, each one pressing against something inside her. He spoke as if he owned her future, as if her life was something he could decide.

Carissa smiled.

It was small, and it did not match the situation at all. It was the kind of smile that did not come from happiness, but from something deeper, something broken.

That smile made him snap.

“You are smiling?” he asked, his voice dropping lower, filled with anger. “You enjoy seeing me like this?”

Without warning, his hand grabbed her chin. His grip was rough, forcing her to look at him.

“You like it when I am angry, Car?”

Her body trembled, but her smile did not fade. If anything, it grew just a little.

“You want to know why I chose to study outside the city?” she asked.

She held his gaze, refusing to look away this time.

“Because I am sick of living in this house.”

Her words landed hard.

“Damn it!” he shouted.

Before she could react, he pushed her back. Her body slammed against the wall, and the impact sent pain through her back. He climbed onto the bed and caged her in, trapping her beneath him.

“You think you can leave me?” he said, his lips curling in a way that made him look unhinged. “I will make you change your mind.”

Then he forced his mouth onto hers.

Carissa struggled immediately. Her hands pushed against him, her body twisting as she tried to get away. Panic filled her chest, making it hard to breathe. He was more aggressive than usual, and that alone made everything worse. But this time, she did not stay quiet.

“Help!” she cried.

His hand clamped over her mouth at once, cutting off her voice. Tears spilled down her face as fear took over completely. With his free hand, he tried to open his zipper.

“Damn it,” he muttered when it got stuck.

For a second, he hesitated. Then he removed his hand from her mouth, using both hands to deal with the zipper that would not open.

That moment was all Carissa needed. She kicked him as hard as she could. Her foot hit his chest, and the force sent him falling off the bed. He crashed onto the floor, giving her the chance she needed.

Carissa jumped up and ran. She did not stop, not even to think. She rushed out of her room and straight to her mother’s bedroom. She pushed the door open without knocking.

Her mother was sitting at the vanity table, busy with her makeup. Her father was on the bed with a laptop.

“Where are your manners, Carissa?” her mother snapped, glaring at her through the mirror.

“What is wrong?” her stepfather asked, his tone much calmer.

His eyes moved over her, taking in her appearance. Her hair was a mess, her face was wet with tears, and her shirt was torn down the front, exposing the black tank top underneath.

Carissa tried to walk forward, but her legs gave out after a few steps. She fell to the floor. Both of them rushed toward her.

“What happened?” her mother asked, panic finally entering her voice.

Carissa lifted a shaking hand and pointed toward the door.

“B-brother…” she tried to say.

“What about Genta?” her stepfather asked.

Carissa lowered her head. Her shoulders shook as sobs broke out of her.

“He tried to rape me,” she whispered.

The words felt heavy in her mouth. Shame filled her chest as she said them out loud. For years, she had stayed silent, just like he told her to. She had endured everything alone.

But she could not stay silent anymore.

“Do not joke about something like that,” her mother said, disbelief clear in her voice.

Carissa froze.

“I will ask Genta,” her stepfather added.

“I am coming with you,” her mother said.

They both left the room, heading toward Gentara’s room. Carissa wiped her tears and forced herself to stand. She followed them.

When they reached his room, the door was already open.

Gentara was lying on his stomach on the bed, casually using his laptop as if nothing had happened.

“I have been working on a report this whole time,” he said.

Carissa could hear him clearly.

“You really did nothing to Carissa?” her stepfather asked.

“Oh, come on, Dad,” Gentara replied with a light laugh. “How could I do something like that? If you do not believe me, ask Kinanti. Have I ever touched her like that?”

He brought up his girlfriend’s name easily, using it as proof.

Then he noticed Carissa standing at the door.

“Carissa.”

He walked toward her as if everything was normal.

Carissa stepped back without thinking.

“Do not tell me you are accusing me because I rejected you,” he said, pressing his fingers to his forehead like he was tired. “I am sorry, but you know I already have a girlfriend.”

Carissa frowned, confused and shocked.

“What do you mean?” her mother asked, stepping closer.

Gentara took a breath, as if he was deciding something important.

“I did not want to say this, but Carissa confessed to me,” he said. “She asked me to be her boyfriend.”

Carissa’s jaw dropped. He was lying. Her mother turned to her with anger in her eyes.

“You are accusing him because he turned you down?”

Tears fell again, one after another.

Everything she had built up, all the courage she had gathered to finally speak, began to fall apart.

She shook her head, but no words came out.

In the end, she turned around and ran back to her room. She should have stayed quiet. It was useless to speak when no one would believe her.
