HOW TO ENJOY
This is not a game to conquer numbers.
Numbers like SWEET and FLUSTER are there to give you a glimpse into Kou's current state.
There are no攻略 conditions such as "You must make the embarrassment level 100" or "An event won't occur unless you increase the sweetness.".
Check FLUSTER right after they say "I love you.".
Check MISS after being apart for a while.
See how SWEET changes when they act cute without any particular reason.
We recommend using it to secretly peek behind the scenes of your conversations, like this.
