[overdoing it with sweets can upset one's stomach, sizhui knows from experience, so he's been careful to not eat nearly as much throughout the week and, if he has a really bad craving, he does his best to choose something that won't overwhelm. after having learned what a sweet tooth he has, it's been hard to resist, but he sees no harm in enjoying sweets, aside from the havoc it can wreak on his insides if consumed in excess.]

I did try recreating the vanilla bean cake once, but... it didn't taste quite the same. However, it was still very good, I just wanted to see if it was possible to make instead of going and buying it all the time. [if it were easy to recreate though, the tea shop wouldn't make as much money as it does now, would it?]
