Baek entered King of Iron Fist Tournament 5 along with his disciple Hwoarang. However Baek withdrew from the
tournament, when he found out that Hwoarang lost from his rival Jin and was seriously injured. He (Baek) then
rushed to the hospital to visit Hwoarang. Although Hwoarang's condition wasn't considered as something serious
after his treatment, he wouldn't wake up and Baek started blaming himself for being an inadequate instructor.

It took 3 days for Hwoarang to regain consciousness. They discussed the details and Hwoarang told Baek
that not only he has to recover, but to strengthen himself even further.

Baek sensed his strong will and his unprecedented modesty and hence he decided to teach him everything he knows.
Baek & Hwoarang returned to Korea, and endeavored to practice intensely. Eventually the announcement of
King of Iron Fist Tournament 6 came from the Mishima Zaibatsu and Baek decided to enter
the tournament one last time, to widen his personal experience-collection.
