So I did a NG+ run up to 1/20 to get all the trophies, cuz I fucked up my time management in the first playthrough and didn't finish two of the social links. Finally did it, also fused the ultimate persona so I'm not complaining anymore. Now that I've gotten my thoughts in order, this is what I have to say:

Life is precious, life is worth living. No matter how little time we have on this world, we should use it to the fullest. The connections we make are important and every single second we spend with those closest with us is invaluable. We don't have to be special to find meaning. All we need to do is live and care about those around us.

Is that an original theme? No. Did it break me, a person who has at many points in his life considered killing himself? Yeah, it did
