Akatsuki no Yona OVA

Yona and her team stop at a secluded hot springs lodge to rest. While the men are in the bath, Ki-ja looks troubled, and Jae-ha's teasing inadvertently reminds him of his complicated past with his father, who is revealed to be the previous White Dragon. Son Hak and the dragons have a drinking contest elsewhere, which devolves into a series of dozes. During this, Zeno has a flashback to his past, recalling his experiences as the Yellow Dragon.
