Gwang-sik wants to understand Hye-ri’s true feelings when she says she needs time. He comes across the “Mind Hole,” a portal that lets him enter another person's mind, and he struggles to find and solve the issues inside. Human relationships are tough because there's no way to know what's happening in someone else's mind. If only he could access the “Mind Hole” to find out! It's a film bursting with imaginative energy.
