Ok so it was really good but I struggled for a long time to get the Souma route.
Here are my tips for anyone trying to get a good ending for Souma
The first one is that you have to invite him to your bday party and then wish for him to be nice to you when given the choice.
Another choice in the game will be in the garden where he talks about how he's not hot. You will be given three choices: Choose the one which says leave him be: then choose primrose flowers.
Idk if this tip counts but I made Yuki boop his nose and I got to the good ending so.
These sound really minor but they actually change the whole course of the story. Every time I did every other choice the same but these two I would stab the president.
