idk what's the problem here, taking too many things on your plate and struggling with priorities is a really common thing to happen. And it was properly set up and everything too.
The forced drama is "Yamada made a promise, circumstances seem likely to get Yamada to break her promise, Kase will be disappointed, etc"
As I said, it is rather more natural than the previous forced drama of the race. Feel obliged (especially in Japan) to (a) your employer and (b) much older women is pretty plausible.
OTOH it's coming not long after the race BS, and the author made up the employment pressure to apparently insert more drama, so many of us are tired.
If Yamada learns from recent history and actually holds a line, we'll change our opinion, but right now it's "oh no, not again". Author burned up her credit with the race stuff.
