Okay so after the update release I like anyone else who wasn't already a patreon subscriber was quite confused as to how we are meant to acquire the fabled shower scene but I finally figured it out
Basically it works exactly like how we get the stove, first we have to get out of the riots which start at day 28 at the latest and last 5 days if you pass the first mini game and are shorter if you fail it at the cost of a chunk of your sanity bar.
Once the riots have passed when you walk outside alone again. (I don't know if its rng it happened as soon as I stepped out so it could be guaranteed as soon as all requirements are met) when you step out the landlord should cut you off with a bunch of ,miscellaneous dialouge about how he evicted another family and he'll offer to put a door between your apartment and their bathroom for 100k and a 1k increase to your rent (how fucking generous of him 😒) accept that offer and after that he'll leave for about a day or two and then he'll come back for the 100k in a suitcase. Once he takes the money he will leave again and on the very next day he'll kick you and Jun out for two hours in which a kinda funny scene takes place.
Once you return, you'll have the door in your room that leads to the glorious shower scene :)
There are probably a bunch of other requirements for both the riots and for Landlord to show up that I didn't cover, I figured out most of this on my own so I don't know anything like specific sympathy cause requirements since my bots sympathy is perpetually super high because I constantly show her affection (im so fucking pathetic)
Klahtune will probably come later and do a proper guide so stay tuned for that if you're still confused
