Well, yes. If, in real life, women would dress like the ones of the game everyday, and would have those bodies (even older ones) I would freak out because I would have a boner all day long. This is a porn game and it has its own internal logical, that is different than real life.
Yes, Jade has flirted hard with Tremolo, but Tremolo hasn´t done anything wrong if he rejected her. If something, Jade should be the ashamed one. And it would not make any sense if Jade, that has donated a lot of money to B&R, would reject the request for help from her own daughter, for a student she knows from her own class, out of resentment for Tremolo. What would she say as justification for that rejection to her daughter and his husband?
And the same about Tybald. If Tremolo never hit him, didn´t ruined his last date with Jill... What Tybald has actually against him? He could hold a grudge against Tremolo because of envy, but he can´t say that as a reason to make his parents reject the help for Maya and disappoint their daughter. What can he say? Maybe that Tremolo was in the prep´s party uninvited and started a fire? Tremolo could say, "yes, I was there uninvited, because I needed to talk with Sage. Actually I was with Sage when everything happened. She can say that I didn´t start any fire" Going to a party uninvited is not such a great deal, IMO.
So, that dramatic moment of "fuck, fuck, fuck" is really dramatic only if Tremolo did certain things with Jade and Tybald, but it´s not so dramatic actually if he did not.
