Bima fell silent at Galang's answer.
"You?"
The single word left his mouth, filled with confusion.
Galang nodded slowly.
"Yes, Bima. Everything Arga has done all this time has been connected to you."
Bima stared at Galang in disbelief.
"But why me? I'm nobody."
Galang walked into the warehouse. His steps were slow, as if he were carrying a burden he'd kept hidden for a long time.
"That's what made Arga different from me."
Bima furrowed his brow.
"What do you mean?"
"Arga always saw other people as more important than himself."
Galang stopped beside the table.
"Including you."
Bima tightened his grip on Arga's letter.
"I still don't understand."
Galang looked toward Farel.
"You haven't told him everything?"
Farel shook his head.
"I was waiting for the right time."
Galang gave a small smile.
"The right time passed a long time ago."
Farel fell silent.
Bima looked back and forth between them.
"You both know something I don't."
Galang nodded.
"That's right."
"Then tell me."
Bima's voice sounded firmer.
"I've been waiting too long."
Bima's mother stepped closer.
"Bima, listen first."
Bima turned toward her.
"You knew too, Mom?"
She nodded.
"Yes."
"So everyone already knew about this."
No one answered.
Bima drew a long breath.
"Fine. I'll listen."
Galang sat down in an old chair.
"Years ago, before Arga left, his family discovered a document."
"A document about what?"
"A document proving that someone had committed a massive fraud and caused many people to lose what belonged to them."
Bima listened closely.
"Who was it?"
Galang was quiet for a moment.
"Someone close to my family."
Dika immediately asked, "So this isn't just about Arga's family?"
"No."
Galang looked at them.
"A lot of people are involved."
Rani stared at the black box.
"And the document is here?"
Galang nodded.
"Part of it."
"Part of it?"
"Yes. Arga split the evidence into several pieces."
Bima remembered all the clues they had found.
"The first key, the black book, the flash drive..."
Galang nodded.
"Arga knew that if everything was kept in one place, whoever was looking for it would be able to take it easily."
Bima fell silent.
"Then why did I have to find everything?"
Galang looked at him.
"Because Arga trusted you."
"But I don't know anything."
"That's exactly why."
Bima grew even more confused.
Galang continued.
"The people looking for the evidence never considered you important. They only saw you as Arga's childhood friend."
"But Arga knew you were someone who wouldn't give up."
Bima lowered his head.
He remembered all his memories with Arga.
When they played together.
When they fought.
When they promised to remain best friends.
"Why didn't Arga take the evidence himself?"
Galang fell silent.
The question changed the atmosphere.
Farel looked away.
Bima's mother lowered her head.
Bima immediately realized there was something they hadn't told him.
"What is it?"
Galang finally answered.
"Because Arga couldn't."
Bima froze.
"What do you mean?"
Galang looked at him.
"Arga was in danger back then."
The room fell silent.
"What kind of danger?"
Galang clenched his fists.
"He found something he was never supposed to find."
"What?"
"That the person they had trusted all this time was actually the one who had caused all the problems."
Bima looked at everyone's faces.
"Who?"
Galang didn't answer right away.
He took an old photograph from his bag.
The photograph looked worn.
Bima accepted it.
His eyes immediately widened.
There were several people in the photograph.
There was young Arga.
There was Farel.
There was Galang.
And there was an adult Bima knew very well.
His father.
Bima fell silent.
"My father?"
His mother immediately looked at him.
"Bima..."
"Was Dad involved?"
No one answered.
Bima looked at the photograph again.
All this time, his father had always seemed calm and kind.
It was hard for him to imagine that his father had any connection to all these secrets.
Galang spoke quietly.
"Your father wasn't the one who did all of it."
Bima stared at him.
"Then why is he in this photograph?"
"Because he was searching for the truth too."
Bima felt slightly relieved.
"Then what happened?"
Galang stared at the photograph.
"Your father, Arga's father, and my family once worked together to expose this problem."
"But someone found out about their plan."
"And from that moment on, everything changed."
Bima looked at Galang.
"Who was it?"
Galang fell silent.
Suddenly, footsteps sounded outside the warehouse.
Everyone turned toward the sound.
Someone was standing outside.
Galang immediately stood up.
"That's impossible."
Bima looked toward the door.
"Who is it?"
Galang looked serious.
"Someone who was never supposed to find this place."
The figure slowly stepped inside.
Bima held his breath.
He recognized the face.
Not a stranger.
Not someone from Arga's past.
But someone he saw almost every day.
Their teacher.
Mr. Adrian.
Bima stared at him in disbelief.
"Mr. Adrian?"
Mr. Adrian gave a faint smile.
"I'm sorry, Bima."
Bima took a step back.
"Why are you here?"
Mr. Adrian looked at the black box on the table.
"Because it's time for that thing to come back to me."
Dika immediately stepped in front of Bima.
"Don't come any closer."
Mr. Adrian only smiled.
"You still don't understand what's really happening."
Bima stared at him.
"Then explain it."
Mr. Adrian looked at everyone in the room.
"Because Arga never left to hide a secret."
He pointed at the black box.
"He left to hide something that could destroy a lot of people's lives."
Bima tightened his grip on the box.
"And you want to take it?"
Mr. Adrian was silent.
Then he answered, "Yes."
The atmosphere changed instantly.
Bima stared at the man he had always considered a good teacher.
For the first time, he felt that this journey to find the truth wasn't only about Arga.
It was about the people who had been around him all this time.
Mr. Adrian stepped closer.
"Give me the box, Bima."
Bima didn't move.
"No."
Mr. Adrian's expression changed.
"You have no idea what you're doing."
Bima gripped the bracelet Arga had given him.
"I may not know everything."
He looked straight ahead.
"But I do know one thing."
"I made a promise to Arga."
And for the first time in years, Bima felt that the small promise two children had made beneath the mango tree was more than just a memory.
It was the reason he was still standing today.
