Forced is a strong word. Coming into money
could just be part of the story, same as going to B&R - we didn't have a choice to not go to Uni either or not be a good guitarist etc. That's just baked in.
There is also nothing inherently "dishonorable" about getting money. People that win the lottery aren't bad, just lucky. Plenty of stories/movies have a protag getting an inheritance from a long lost relative they've never met, nothing wrong with that - until it turns out that the inheritance is a creepy old mansion with a book made of human skin in the basement that is
).
There is no moral dilemma unless there are major strings/conditions attached. e.g. It could be that the heir to the "Buffet" fortune recently passed away and MC is the only blood heir of the family alive. Grandad decides he has no choice but to name MC as inheritor - but we will only get it on graduation - so the choices will pertain to how the MC behaves as a rich/influential guy on campus and
not a lame game of "choose what to invest in."
Having said that, we don't even know if the letter involves money or not. The chances are high tho because it has been foreshadowed twice. First in our conversation with Jill (where we joke about her buying islands) and second in our conversation with Maya outdoors where she specifically asks what the MC would do if he came into money.
