Yugi decided that enough was enough. He had been having thoughts for awhile. Thoughts such as
"What if Yami only stays out of pity?" or
"What if he just thinks I'm weak?"
So he decided that he was going to leave. And save Yami from his weakness. That he would leave and let Yami find the person he deserves and needs. Not some scrawny little boy that needed protecting.
So, he was packing. Packing for his trip. He had already left a note explaining to Yami so he wouldn't come after him.

He had almost finished, when he heard a knock at the door.

"Aibou? What are you doing? Are you going somewhere?"

Yugi stiffened. He wasn't expecting Yami to be back from working at the Game Shop so soon. This would complicate things. .. A lot.

"Uhm... I was..." He paused, not knowing what to say. Why did the universe have to be so cruel?

Yami walked over to him and studied him, "You were what, Aibou?"

"I was... ... I was packing, Yami."

"Packing? Where were you planning to go? Do I need to go with you?"

"No!" Yugi blushed at his outburst and looked at the floor. "N-No.. You don't have to come with me.."

Yami looked inside his bag. "What are you packing for, Aibou?" He looked at Yugi curiously.

Yugi avoided his gaze and shuffled his feet shyly. "I'm leaving.." He mumbled.

Yami raised an eyebrow. "Speak up, Yugi. I cannot hear you."

Yugi shut his eyes tightly. "I'm leaving, Yami! I don't want you to be sad anymore! Or stay with me because you feel like you have to protect me! I want you to be happy, and I know you can't be happy with me."

Yami looked at him, dumbfounded. "Aibou... Do you honestly think I feel that way? You make me happier than anyone else can! You're the main reason I stayed back in this world! I wanted to be with you and I still do." He took a step closer to Yugi and pulled him into an embrace. "I told you before... I love you with all of my heart and soul. And nothing shall ever change that."

Yugi looked up at him, tears streaming down his cheeks. "I-I love you too... But do you really mean that..?"

"I wouldn't lie about this, Aibou. Honestly.. Did I do something to make you doubt my feelings for you?" He wiped Yugi's tears away gently.

Yugi sighed and looked away. "No.. I just got worried, Yami. It's always a thought in the back of my head. And I just want you to be happy."

"I understand Yugi. But leaving me is the worst thing you could do. I love you. And being away from you hurts. So don't ever think that leaving me will make me happy." He leaned down and kissed Yugi gently. "Now let's get all of this unpacked."

Yugi nodded and smiled softly. "Yeah.."
