Ah yes, Graduation.
That which happens in the season of meetings, farewells, and sweet Vanilla lovemaking.
Great ending though. I assume they were separated for some reason right after graduation, and that ending and last page was after a short time skip, I would imagine? Well hey, I'm certainly glad they could reunite, and I'm sure they have a lot of catching up to do...
"My mom's gonna hear us." - Natsumi. 99 times out of 100 in the H-Universe, a mother WANTS to hear that their child desires to lose their virginity.
Kouta was portrayed as hesitant to the idea ... at least until Natsumi used "touch my boobs" - Switch Flipped Instant ON!

Ah, well ... it got the job done, and sometimes, that's good enough.
