This was written right after Enstars was released, and I think I remember the mini event choices were listed in the same order every time? It became randomized after a few days, but at the time, the third choice was the "correct" one—meaning it would always increase your fever in Akiomi's events.

Since that won't always work anymore, you can check out Akiomi's mini events page to make sure which choices increase fever and which one lowers your luck!
