i would disagree with you, there is much "drama" in other parts of the game story without having to touch on the main triad (the MC, GF and his BF).... for example the MC needs to keep wining games in order to keep the coach's job, there is also talk about a scandal at the university and how they want to avoid futher talk of suspiction (it would be very scandalous if it got out that the MC the star player of their team plays hide the salami with both GF and BF not only that but the MC mom is cheering them on).. there is also the whole other storyline about the MC biological mother and father history (like in real life once an athlete get famous all of a sudden their deadbeat fathers finds them and want to connect and make up for lost time, i'm sure it has nothing to do with the money or fame
)... oh oh then there is the other other other storyline with the principle where i think he could be a pimp but i also suspect that he is also selling drugs, anywho he looks like that type of character to bet his life savings against his own team then ask the MC to take a loss....
TLDR so in short there shouldn't be any shortage of drama due to all these plot points and many more (game dev if you read this then plz use these plot points its too good to pass up
), IMO i think adding drama in the relationship between MC/GF/BF and MC's Mom would be overload and too much to keep up with and will burnout the game..
.... but hey its just my opinion
so take it with a grain of salt..
