Game Plot
So, you decide to order a special product, a strength-boosting serum that you happened to come across. It claims to make you taller and more muscular in just one night!
Without hesitation, you inject the serum into your body, hoping to prepare for a strength contest the next day. You're determined to get rid of everyone standing between you and her. It's the only way you'll finally get a chance to talk to her!
But then, something unexpected happens...
The serum you injected has the exact opposite effect of what you expected!
Instead of helping you win the heart of just one girl, it gives you the ability to win the hearts of girls all over the world!
