Too much salt instead of sugar, what sugar remaining is on fire is a good metaphor for me.

[Of course Kimi goes with the cooking metaphor. It's not wrong though. They're all doing their best to fill in all the blanks with new experiences or uncovering what they already know. It's not as if she's had the hardest time with things; Waver comes to mind as an immediate example of someone struggling against the edges, chipping off more as he tries to make it work.

Maybe the first year is always hell. Can she even make it a year?]

How long did it take for you to realize you were good at cooking? Not metaphorically speaking.
