Call me crazy, but I'm pretty sure Nozomi's taken a turn for the worse because she realized that Shino is finally starting to move on. She's been holding on to Shino with all of her might because she is the last remnant of Taichi in her life. But now it feels like that last thread is slipping through her fingers.
I'm not expecting a full psychotic break ala "School Days," but there is definitely gonna be a point where it all comes crashing down for Nozomi; and Shino's gonna have to gather all the King's men to put Humpty Dumpty back together again.
Like the old adage says, "It's not about falling down, everyone falls down, it's about getting back up again." It took 68 chapters, but Shino was finally able to stand back up.
Now if you'll excuse me, I'm gonna go read 200 chapters of "Okusan," because my heart can't take much more of this grief porn. Somebody message me when this story gets fluffy again.
