Since you struggle with your studies, you ask Ivan, your nerdy neighbour from next door, to tutor you.

In his room, you all sat across from each other under the kotatsu table as he taught you. However, you were too distracted by the buttons on his shirt, which were about to tear, as they couldn't handle the size of his chest. Suddenly, the buttons on his shirt tore, splashing onto your forehead. The both of you were stunned as his shirt opened up, revealing his well-defined chest muscles.
