Me too I don't know the ending of 3 date mochi, I looked at the dialogue the same, I saw in the game files it should be ⚠️spolier?⚠️ ending of 3 date mochi in the hot spring the lights are on
i found a way to get the third ending, i don't know which option triggers it but i picked these:
>Mochi...?
>It's too dark to see here...
>(struggle against your restraints)
>(keep crying out)
>No, it wasn't me!!!
>Wh-what are you gonna do with that knife?!
>I thought this was supposed to be a dating game!!!
