As far as Platinum trophies go for otome visual novels, this was the absolute easiest to get. It’s pretty impossible to make a mistake and get locked out of an ending, unlike the previous two of Aksys Games’ summer of mystery. So why bother with this trophy guide, then"
This is the most efficient path to nabbing each and every trophy. Less time wasted, less frustration in “why in the world can’t I open that branch in Chapter 3 *1" I see that branch right there, so what have I done wrong to not get it"” (I totally never had this conversation with myself. Also never pulled my hair out wondering why I couldn’t unlock the “Stranger” short story. Nope, never happened.)
As long as you follow this ending order, do all of the short episodes and Town Memories as they open in each Map (don’t forget to switch between Jed and Eiar when available!), and purchase everything you can in the Antique Shop, you will procure that Platinum in no time. The bronze trophies for completing the individual chapters and getting 50% collection rates are not listed, as following this guide will automatically unlock them. Happy Ending I (People Ending)
Easiest ending to obtain by far.
