Sorry, to double post. Just wanted to post more comments/questions.
1. I know we have to beat all of the lives for each of the 6 major lives in one year, but is that just for the trophy? Or, is it also for the end of the year review as well where the president reviews the major lives done? (Sorry, for the dumb question). Reason I ask this is because when I decided to give 1 major live a try out of curiosity, the president seemed to give me credit for IU (I believe) even though I didn't do all the IU lives. Thought, it was kind of weird.
2. I noticed certain unlisted lives stay on the menu list even after beating. However, the character unlisted lives seemed to disappear after beating. So, there seems to be no way to know to check to see if you beaten them. Guess you just have to remember it.
3. It seems using the trend outfit gives you boost in appeal scoring. But, I tried using the trend song, and it seems to boost the full combo score. (not sure if it does anything else.)
4. I also noticed after I got Miki to S-rank, her same morning office scenes (and I think evening office too as well) change a bit where she greets and calls you honey instead. I don't recall it being like that in PS. (though its been a long time)
5. There a few S-rank SP lives in the last couple months where there's a ??. Are those for you know who? (did the spoiler button just disappear?)
