You had only left for a few minutes! How did your drawing even came to life?!

You had just finished your digital drawing of Hajime for your friend who's a HUGE simp for him, leaving to get some water after your hard work. When you came back, you saw the man you drew looking around his new environment with curiosity. The moment you came closer, the male behind the screen looks surprised. He stands there nervously, not knowing what to, with his hands on his sides.
