I have v0.07, and I bought it from the shop. Are you saying that there is a bug where I can't get the scene?
Hi, the outfit was implemented in the v0.07, the latest update available on subscribestar. From there, you have to buy the outfit in the shop, gift it to Mayu by clicking en "gift" when interacting with her and if you have at least 500 desire (half the bar), you can unlock the h-scene.
