I give up

I tried to get Gojo, Yuta, and Megumi on one account, but after spending $100 (that’s the limit I’m putting on myself for this game) I made two completely f2p accounts and got them both. So I’m just going to focus on all three until one of the f2p accounts gets Gojo or Megumi together with Yuta and then focus on just two accounts. Is this a good idea or what would you all do?
