Treasure And Torture

You have someone who desperately wants to be your friend.

BUT...

That person is a terrible, insufferable burden you want nothing to do with.

HOWEVER...

Their parents are Super Rich and will allow you to use anything of theirs you want as you're their lonely child's friend now.

SO...

You "learn" to put up with your "friend" and their horribleness so you can have access to the cool stuff you want.

When someone in the Main Cast, like the Main or someone close to them, is introduced to an issue, typically an annoying person, but does not have the courage to deal with said issue properly, then is later introduced to an upside to dealing with this problem and eventually forces themselves to endure whatever it is they don't like. This person can be somebody trying to begin a positive relationship with the Main Cast's member, such as a friendship, but is hard to be around due to how undesirable they are. However, this person is related to someone who is willing to offer something to the Main Cast member if they remain friends with this awful person. Naturally, they let what they want overrule their hatred for the terrible one and try to maintain whatever relationship they have with them.
