What was he originally wanted to do? I mean I didn't play early updates
It's not like it was massively different from what it is rn. The only thing I can remember is that it was a classic setup of you returning to home for Summer vacations. You meet with your cousins and aunt. They get excited. Your Amelie kisses you. It also tells that MC already had a crush on the aunt.
Amelie storyline- same. It was about her and Davie relationship. It was. Just fast, like you already had got the date event of her and Davie
Kylee storyline- Now this is what I was talking about, this was about her and her boyfriend. You can say it was like a prequel of the VN game. She was trying to do something about their relationship. In this sandbox, we had the options of sleep sex(though the dev had only implemented hand/blowjob at that moment.
I didn't played the Stephanie storyline coz I was already frustrated because of how clunky the sandbox was.
