So, going against my normal stance of not playing games with locked content. . . I've chosen to continue playing and just realized something, aside from playing with Hitomi a little bit, there is very little actual sex, at least where the MC is concerned, there's a lot of OTHER people fucking, but for the most part, the MC just sees it happening whether it's in memories she's viewing or stumbling upon people fucking, is she some kind of celibate succubus/lust demon? Or is just meant to be a VERY slow burn?
No MC is not meant to be celibate. I don't know exactly how far you have progressed, but there may be a few reasons why you feel this way. The biggest one is that the balance between academic life and the main storyline is quite out of balance at the moment. The main story is much further ahead.
In daily life, the MC is more of a leading character, whereas in the larger main story, the MC is more of a witness and trying to keep up with everything. This is mostly a intentional choice, but it may stand out more because the balance is off.
To gradually stabilize this imbalance, in patch v0.7.2, a new character and her seven scenes added to the early game. And for a while I intend to progress mostly the early game and other dormitories. Also in Latex Dungeon storyline, the last few scenes were MC-oriented. In v0.7.3, if Latex Dungeon is chosen in the poll, the sex scene will be MC-oriented again.(You may not have reached these scenes yet.)
Normally the next patch theme is determined by supporter polls, but the v0.7.2 patch was determined by my initiative. With such initiatives, I will continue to advance the Newcomer's Dormitory and its characters. Still, there will always be more side character action than in a regular HTML game.
Also glad you have decided to continue playing the game!
