Sorry guys for that ;-; I fixed this bug in version 0.23.
As a temporary solution, you can try to increase the intimacy point with another character instead of the girl with red glasses (WDIS), she's probably the one with a bug on the checking code :v
Class president (WPRE) and pervert dude (HPRV) should be the safest try (I guess), but others may work too (I guess).
Consider joinning our discord and sending me a message there if you need ^^
