Ah...what a flattering thought! [Komaeda laughs.] To think that she'd do nothing while she was here, purely to let me taste the ecstasy of despair of being denied by her...! That she'd place so much importance on me...! [His eyes go...a touch wild for a moment, but they quickly calm again.] But no...I'm sure she'd never do that for someone as worthless as myself. To not spread her despair purely to spite me - I can't imagine her bothering with that kind of restraint on my account.

I expect she just didn't have enough time to set whatever plans she had in motion before she disappeared.
