Mokuba was the one who was diagnosed with cancer. Mokuba was the one who had to undergo chemotherapy. But Seto was the one who's heart broke. His heart broke each time he found clumps of Mokuba's hair around the house. His heart broke each time he found Mokuba curled up in his bed crying. And his heart broke each time his little brother asked him why, and Seto was unable to answer him.
It had been two months since they found out. Two months that Mokuba had been undergoing chemotherapy. And two months of Seto watching painfully as Mokuba's hair got thinner and thinner.
"Big brother..." Seto's eyes wandered from his locket to look up at his little brother, who stood in the doorway of his bedroom wearing his long pajama shirt and looking sickly pale. Seto shut his locket and hurried over to Mokuba. "I'm so sorry, big brother."
Seto picked up the child and hugged him tight. "Why are you sorry?"
"You always told me you loved my hair..."
Seto's chest tightened. "Oh... Mokuba..." He felt hot tears spill onto his shoulder and found his own eyes threatening to water.
"And n-now... it's g-gone..." The child cried into his brother's shoulder, small hands grasping Seto's arms tightly as he shook with the force of his sobs.
"Mokuba, don't... It wasn't just your hair that I loved, little brother." He pulled Mokuba back to look at him and brought his fingers up to gently wipe away his tears. "It was you. It is you. I love you."
The child's eyes looked to the floor and he spoke in a whisper. "I don't want to leave."
Tears formed at Seto's icy blue eyes and he shook his head. "Don't say that, Mokuba. You're not going anywhere."
Mokuba began crying again, burying his face into his older brother's chest. "Don't lie to me!" His voice was muffled by the older's shirt. "I don't want to go, Seto... I don't want to go..." He looked up at his brother and sniffled. "I love you..."
The brunette ran his fingers gently through the little amount of hair left on his brother's head. "I won't let you go, Mokuba."
"I love you so much, big brother." The child clung to the other tightly, eyelids closing over gray orbs.
"I'll never let you go."
It had been two months since Mokuba had been diagnosed with cancer. And it would be two more months before the doctors would tell Seto that it was already too late.
