choosing only 'no' will lead you to a different day/storyline, which has 3 possible endings. ending 5,6 and 7. when you get that different storyline, try the instructions of the 6th and 7th ending! ending 6/7 can also only be achieved by the 'no' run, like ending 5 ^^
you don't have to! just ALWAYS choose the 'no' option in a route! it is the opposite of the ending you only choose 'yes'. only choosing no will lead you to a different day, like in the 'yes' ending.
the art is so cute and pretty! it really fits the aura and story of the game. the story is very relatable, espically if you are having a hard time to confess to your crush :'3
gameplay and story is so good! i am a fan of ritual stuff in games/movies, so I adore this. main character is so cool too, and endings are *chef's kiss*
