Everyone Gets Drunk (Island Life of Mutual Clubbing)

When things don't go quite as planned for a certain simulation, people begin to see the future (or at least, a bunch of past loops), and their efforts change an awful lot - though not necessarily for the better. And when alcohol's brought into matters, things only go downhill from there. (SDR2 with glitches, drunks, and time loops. Souda/Tanaka/Saionji/Koizumi/Mioda shipped.)
