The Happy Ending for the Grand Route.
In other words, the true Happy Ending.
Also, there are no choices in Day 5 and the ending will diverge based on the choices you've made thus far.

At the very end, it's a happy result for everyone, but I wonder if they all know what Syouko and the others have gone through...
