On page 6, we saw that Makoto paid 2 gold coins for the wooden bowl. Note that this was also referenced on ch 27 pg 19. Basically, he met her around the first week when he arrived in Tsige.
I am both impressed and hating on how the author/artist often do this stuff. Like they didn't fully explore what MC did in early chapters, but then retcon something ~50 chapters later. This would have worked better if this isn't monthly (and only 11 chapters per year).
With how it is now, it makes it hard to understand the timeline. Even in the previous chapter, it's confusing how they mix the trip to the forest from the past and the present.
