You might want to go check out the rooftop at the school if you haven't been there yet, the skip is generally just if you want to see what's there at first (at the end, but in hindsight the skip might have been a slightly poor idea), but playing through all of it the skip isn't necessary (if you hit all the events, you get to the evening still).
(also it's unclear, but you can't enter your own house again after you leave right now, I should probably clarify that which I will with the next patch ^^)
