My bad, changed my discord setting just now. You can add me now.
And you can buy clothes from shop, give it to fuyuka, then change clothes at room UI.
Sent a request on discord.
Also there's no room UI. My only options are bathroom, Fuyuka, bed and kitchen. Is it further down the line?
Also I just realised I never got a 'Demo End'. I got the Key Item and it said this was the last event but apparently something was supposed to happen. Do I need to further romance levels or am I missing something?
