Peter is a young man who has been physically weak since childhood. Despite being smart and brave, he doesn’t have the strength to stand up to Johnny, a bully who constantly makes his life miserable. He also has a secret crush on Celia, a girl who seems far beyond his reach. But as he tries to get closer to her, he finds himself caught up in mysterious events, hidden secrets, and encounters with people who could change his life forever.

After a lifetime of being weak, Peter finally wants to change his fate… But what will he have to sacrifice?

Game Plot
You’re just an ordinary student who has a crush on a girl at school. But no matter what you do, you can’t seem to win her heart. It looks like she likes another classmate, a tall and muscular guy who happens to be your rival!

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!
