I really want to get back to the present (and see what happens with Hwang, Marlene, and the rest of Munsu's future allies against Aji Tae), but at the same time, the length of this flashback shows how deep Munsu is trapped within the mandragora's hallucination. But, since it's not just random, and certainly not as happy as it is supposed to be, it shows that Munsu will be able to work his way out of it.
