For one, I starts to agree with author that this direction have an upside on the relationship and maybe more 'realistic' in a sense.
Instead of him homing in on Agawa just like before which make the story progression become more difficult (whether or not it has to progress in the previous direction is up for debate, but I can see the option really narrowed down by magnitudes), this direction does have more interesting options open. Of course, a virgin having sex for the first time, the experience is gonna be lasting. Of course, when a beauty such as President asking to have sex with him, let alone a shimai-don three-some, he wouldn't be able to refuse. It's also very relatable that he will catch a feeling with anyone he had sex with when he was just a virgin, like, a few weeks ago.
And now that he really searched his feeling, it is tremendously more meaningful for whoever he settled down with in the end.
But... well, the same would also applies to Akito, right? I... don't really want to see it, but it's only fair...
