Joey Wheeler ran away from his abusive father in America and wanted to start a new life at Domino, Japan. He never expected that he would meet and become a roommate with someone who look like him named Jounouchi Katsuya.

Jounouchi suddenly wants a girlfriend, or a boyfriend.

Kaiba was always annoyed with the friendship in Yugi's group. But he never imagined he would feel dissatisfied while watching their friendship falling apart.

Kaiba finally agreed to become friend with Yugi's group. Jounouchi was curious at first, but then he started feeling like he was falling out of place while Kaiba was closer with his friends. But the worst part was when Jounouchi found out about Kaiba and Yugi having a secret...

Eleven years have passed since Kaiba's brothers went to America, Kaiba woke up and realized he have been in coma for nearly six years. Since Mokuba did not let him go back to work due to his health, Kaiba decided to come back to Domino. Have the old place changed after eleven years? And the people he knew?

Life could be good. Life could be bad. All of the good things could suddenly become wrong or vice versa. Jounouchi experienced it from his own life and from people he knew. He met Mokuba again after over ten years in Domino and had a conversation with him.

Jounouchi went to Kaiba's mansion to help decorate for Christmas. He then saw the strange plant under the doorway into the living room and decided to ask Kaiba about it.

The gang were stuck sharing a stormy night in an old castle when they were on the way to Kaiba's mansion on Halloween night. Strange dream came to Jounouchi with music, dancing, and... Kaiba. But was he the only one who had that dream?

After four years of dating and living together, one day Kaiba called Jounouchi into his office and asked for the repayment of his debt.

Jounouchi always laughs and pretends nothing happens in his life. But when he's having a problem and knows himself can't stand it alone, will he let someone help him?
