How to unlock piano game in Monika after story ddlc mod mas

I don&have the piano game so I cant confirm if this is true but this what reddit was saying so I&guessing it is true. If there are any other guides you want me to make let me know what you want me to do. 1. play the game for 150 hours (just minimize the game and do other things) 2. Get 400 affection points 3. play the other games I play a ddlc fan mod called Monika after story also known as mas most of these videos are of Monika talking about things or playing games with her. What mod should I play next? comment the mod name and I might play it #monika
