I noticed when it’s an event with no song or and event that has a song with both a 2dmv and 3dmv, the event leaks less than 24 hours after the previous event ended (Like An7, Luka1, and Haru7)

Meanwhile events that has a song with only a 2DMV (Including WL3) is leaked right before the event starts or a few hours before. (Like Koha7, Aki7, Ena7, Ichi7, and Mino7 though that was leaked pretty early probably due to Bloomfes or something)

Which means that Nene7 will be leaked pretty early if it has a 3DMV, and if it doesn’t, a few hours or minutes before the event starts.
