Romantic Blossom Academy Relief Pitcher Training

As the title says. Power Championship is over, so I challenged myself to train a relief pitcher. The result was Yellow J23, my personal best score! Well, I couldn't get the 'Strong Heart' skill due to lack of mental stats. It's frustrating to be just one bar away from 24. My future goal is to someday reach 5 million points. I want to make a good player next time too!
