when we have a romance with Jeremy, we don't have an object that fits the BBC theme, we have the character Jeremy. i mean sure, you could include some BBC play in that relationship, but it wouldn't be the same as when the BBC kink is your focus.
I'd assume that if a romance route were to be made for Jeremy, it would be made
in addition to the pure sex/BBC kink route - like what was done with Minerva. In other words, you wouldn't have to get to know Jeremy at all if you only cared about his dick and not him as a person. In fact, besides the odd unintended public 'moment' with the group, Jeremy would remain largely a closed book as he's not beating down anyone's door to show them the nerdy personality he's pushed down for so long. But if you wanted to be in some kind of relationship with him you'd have to make the effort to get to know him, and discovering his true self would be part of that. I don't begrudge fans their BBC kink, but there's no reason why Jeremy can't get the same treatment as Minerva with her pure sex route (and all its little kinks) and her romance route, especially when one doesn't need to interfere with the other.
Incidentally, if you truly wanted a character that existed to satisfy your kink with no burden to get to know them and no personality to get in the way, a character with a cameo-type appearance would be much more suitable to fulfill that purpose/role. Someone who has one or two scenes tops, and then they're gone again. At least that would fall in line with the MC's 'didn't get to know them because they're not important in my life' excuse, rather then someone who is the best friend of one of the two MC's the player embodies, and where knowing each other's personalities goes hand in hand with being best friends.
(Couldn't remember if Jeremy was Ian's best friend or just one of his closest friends, but it doesn't really make a difference in this case.)
