Normal; Final Score: 462
So uh... I initially thought this tabletop game was multiplayer and ended up gathering a couple friends for it only for us to all slowly realize... wait a second, no it aint multiplayer, and all kind of just fumbled about doing other stuff for the night instead...
Anyway, to detail my playthrough: I kind of just set things up so I could ignore basically everyone after a point. I was playing on normal so I could kind of just ignore tsukasa from the get go since her relationship up requirement is kind of hard to achieve and she couldnt decrease her relationship ever, and with her starting at 0, well... that was one person I could just ignore. Next, momoyo's relationship, it never ended up going down because any time I tried influencing the market, Id try to influence it for positive increases across the board, banking on the stock divisions and making sure I always had at least one stock in everyone for those divisions to matter. This meant the only person I needed to "care" about was chimata, which uh, I just kind of let rng roll for the first few turns so she's like me and dated her a bunch until she liked / loved me. Those free stocks of my choosing from chimata were really useful and let me never worry about the "buying" part of the buying and selling stocks again. I just kind of coasted for the second half of the calender selling some of the stocks I have fuck loads of just so I can try to influence all stocks to be closer to splitting up into more stocks. Honestly, if I read ahead into the calculations for a winning score and knew that multiple loves influenced it I might have spent the last 4-5 months trying to maximize the other's relationships instead of coasting on my fat stacks of stocks, but eh well. Cool board game, wish I didnt mistake it for multiplayer and gather a bunch of people for it
