Yugi, Yusei and Yami brothers

Yusei feels abandoned and lost, so he tries to seek help from his friends. They don't realize and slowly push him away, causing him to lose the bonds he has with them, closing his heart to them...forever. Yusei flees after a the final break, taking his deck, some personal things and nothing else, to the past, to Yugi Muto and his partner Yami, where they start to care for him. Everything seems to be looking up, until Yusei has to go back to his time, where everyone who destroyed him remains, and haven't changed at all. What could possibly happen?
