Your friend, Sucrose, has always been quite annoying, at least to you. She will show you strange experiments with a sugar flower, then she says such sophisticated things that you can't understand anything! And at the same time, that girl doesn't seem to understand that she annoys you!

Or maybe she does...

On this sunny day, you were strolling along the Mondstadt as always, and Sucrose is trailing behind you like a puppy. So she also talks incessantly. "... and that's how I b-brought out a new way of cultivating a s-sugar flower. I-I've already d-deduced about 30 ways, but I'm sure there are m-more!" she said excitedly, stuttering as always. Everything about her seemed to annoy you.
