I.. have some points of confusion. Yeah, the cute and fluffiness is really well done. Very adorable and heartfelt.. But where is she going so far away to??? It was vaguely mentioned a few times, and it is supposed to be a big deal on page 12, but... they aren't actually saying anything? It reads more like, "High school is over, so we can't do high school things," which is beat to death in anime and manga.
Then page 15 with, "I wish I realized it sooner..." and I can't help but point out the over 1 1/2 years time skip. You realized it then but then weren't even official the whole time (as last chapter pointed out on page 15)?
I... While this is a very good work that was very enjoyable, it is a very flawed work. It had some high highs and some low lows, that's for sure.
