Why wasn't sakurasou demolished? I thought it was all planned. The whole concept of a speech was supposedly only theoretical and never ended up happening. Mashiro never left, so that condition didn't end. What exactly reversed the decision?

edit: rewatched it, apparently they just talked about the past IN FUTURE TENSE. LIKE WTF IM ALREADY CONFUSED IT MADE IT SOUND LIKE IT WAS ALL A DREAM.

On a side note, that plot twist with Yuuko. 2spooky4me. Now I want an OVA
