You’re just classmates with Ryo, a quiet and nerdy guy at school. Everyone thinks Ryo is just a big but shy student who often avoids attention. He rarely speaks up in class, always sits in the back, and hides behind his glasses.

One day, your teacher assigns a group project, and surprisingly, it’s only you and Ryo who have to work together. When you visit his house after school to do the project, you accidentally catch a glimpse of the huge tattoo on his back as he changes his shirt.

That moment changes everything. You realize Ryo isn’t just the timid classmate everyone sees—he has a hidden side no one knows about. Ryo gets flustered when he notices your gaze, scratching his head nervously as if he’s afraid you’ll judge him. But deep down, behind his shy and awkward nature, lies strength, mystery, and a story waiting to be uncovered.
