A little helping hand by yours truly as in - a "guide" of sorts - because I did a whole bunch of things without any screw up on my first (aka current) playthrough and now I'm going through the cohabitation part.
Now I don't know which translator do you lot use, but one thing before I do start this off - have some patience if it's an auto translator. It takes a second, or sometimes a few seconds depending on how big are chunks of text (as some of the text can be rather chunky ngl especially when you start taking the job more seriously and start unlocking all the materials and whatnot and the log gets filled).
So let's go.
-First off is -
AVOID all of Marina's advances until the first portion of the game (19 days countdown) gets finished, otherwise you're locking yourself into a different end and you're not getting to the cohabitation portion of the game. The way to dodge these is picking the dialogues that
WON'T lead to any ecchi/sex scenes. I believe you also have a writing that says something like
"Activate Buddha Heart" on the choice that is correct.
-Be nice! Be patient, be nice, talk to her, headpat her, don't peek at her in the bath or toilet, don't play the lewd game with her. After 19 days you can go ooga booga xD
-When she comes over at one of the nights, and offers sex -
REFUSE. You're not in the clear until the 19th day.
-Storm event. When the storm hits, and Marina comes to you, hug her.
-After a certain event, she'll grow distant for a few days, like cold, won't eat dinner with you, won't talk to you etc - don't worry, it's not a screw up.
-On final day when she is about to leave you'll get a choice of either just greeting her/telling her goodbye (depends on translation) or telling her to wait. If you tell her to wait, you'll get to the cohabitation part.
-Money isn't that big of a problem in game, just sew a clothing every 2nd or 3rd day (don't forget to sell it on the same day as well so you get money tomorrow) - this'll also do you well. The more clothes you make, the better your cash flow gets. Sometimes even make something 2-3 days in a row and then spam sell it. My current highest sale was around 40ish k from 3 clothing articles.
-One positive thing is - you don't have to worry about food like in some cohabitation games, so that's a plus.
-Once you unlock the bookstore, buy the damn books. You'll get more point progress with job/ero/appreciation stuff. I used the books on workdays when Marina's at school.
-Take her out on weekends, either to beach or park. Yes you can also take her to bookstore and material shop (shop where you buy things for clothing designing or books for progression) and you can go to cafe after. Sometimes you'll get to make the order at the cafe sometimes Marina will do it. Regardless it's a good appreciation farm.
-For H - you'll have to be patient there for a few days. There'll be an event during cohabitation portion after which you'll need to gradually open her up to things. Kiss her. And see her out (written as "Saying off" in the menu) when she's going out on workdays in the morning. Eventually she will come to you at night and ask for H. Ofc it will be short, but you get to develop her body bit by bit. Focus on all areas.
-Another good thing for H after you develop her is - when you hover over a body part, use a mouse wheel, you'll get to scroll through more options. Read the notifications that pop up on the right side of the screen (the log where you read what have you unlocked/did so far) it'll tell you if you have any additional options.
-Costumes are ordered through phone - once you start doing H things, you'll get another tab unlocked in the phone menu from where you can order things. They'll come tomorrow.
That's it for now. Good luck with your agonizing 19 days
