There are 2 ways for that :
First you can watch cartoons at the cinema for 2.500 yens.
Or second, you donate money at the shrine, the more you give, the more affectionnate you'll be
Hope that helps ^^
I'm sorry for asking, but do you know how to get the "erohero" audition? It's on the auditions guide (https://docs.google.com/document/d/1P6iYaiVrfa9TLpGbv7B51TocGv3zhcPUK89HzrbKyIw/...) but I don't know how to get it!
Don't be sorry for asking ^^ But well, I also don't know how to get it :/ I think I once saw the name in game but I don't remember having done it, also, the "pained" option isn't available in the mini-game, so it's weird ^^' Sorry, I don't know it ^^' But don't hesitate to ask something else, I'm glad to be helping ^^
