Yumi's Cells

Eunjo is an ordinary office worker who lives by the personal mantra, “There’s always tomorrow!” She’s lazy, messy, and clueless when it comes to looking presentable. Her colleague Wan Jo is the polar opposite. He’s religious about self-care, and particular about his carefully constructed image. But they both have something in common: they’re constantly at war with their past and future selves. (Source: WEBTOON)
