This work is painted with acrylic paint on wooden panels and cardboard. The paint applied over the cardboard appears with each stroke, bringing changes to the form. The "hearts" in MONKNORI's works are simple in shape, yet express complex emotions hidden within their soft curves. At first glance, the heart is perceived as a symbol of love and joy, but MONKNORI's work reveals the deeper emotions and inner conflicts of the heart. The work depicts the complexity and multi-layered nature of the heart with gorgeous overlapping colors, evoking the "invisible heart". acrylic, cardboard on wood panel
