I don't really bother with 4 and 5 stars. I am still working on getting them all to 3 stars. Costs of affection is too high compared to possible income.

But that is only one of many problems in the game. Another is the lack of something to use energy on while waiting for the next part in the questline, losing out on a lot of points for contests that way, and absolutely nothing to use their "big" Black Friday discount for, which in turn means no koban sale for them! Pretty bad step when you want to sell something!

It is a nice game, but veterans are being punished when max energy just sits there.
