So it has an okayish structure. Other similar games with grind it's a bit better and a bit worse in some ways. The random events are nice for scenes, just need to pad them out/make them a bit more varied. Some annoyances, like when you get the flow going, when you wake up you have the option to go straight to class, but you don't. You still need to do some button presses. I could see how you want some minor time slots left open for future characters/teachers, but it feels bad a button like that is there and it only save a few clicks, instead of just shooting you forward.
You have other similar things that aren't quite the worst thing in the world to deal with compared to other html's with similar structure, but like it makes it a bore, especially with how slow progression is initially(or without cheats).
My only other issue, and its my only real issue, is the girls picked. 3 slightly different version of white girl, with the spectrum being nerdy, wall flower, and blows you for a poptart. The asian teacher scenes were more refreshing(although I need busty asians to feel the love tonight~~!) if only because I didn't know without specific names or prompts, which white girl I was seeing a scene with. I suppose if a girl had like C cups, it had to be our girl sucking us/others off for poptarts, but like pretty boring girl collection to start with.
All in all: not too grindy (maybe a 5.5/10 right now with grind), button selections for actions is somewhat rough/poor (4/10),scenes and scripted events are fun, and what I expected (6.5/10), I appreciate that you didn't make ntr/bbc combo too annoying or like over bearing, but it could still be written better that doesn't involve them just making the MC a cuck with 0 training (5/10) and finally you need new or better girl choices than three different versions of white bread man, I'll give credit for the asian but where are my sista's, latina's, indian's, and so on?! (3.5/10).
