Monika is a university student who works at her Uncle Namjoon's cafe. Life's great but it gets better when comes in Benedict, who causes her to forget how to breathe. He makes her feel crazy just by waving or smiling at her. He causes her to get butterflies in her stomach. His beauty causes her to scream till her throat hurts. He lightens up the cafe just by his presence. His eyes shine brighter than the sun whenever he smiles. He is the cause of her euphoria.
