On a rainy night, Rain, the quiet cafe owner who has long locked away her heart, encounters Punpang, a lively intern seeking shelter from a storm. With her playful, cat-like charm, Punpang gradually fills the empty cafe with so much warmth that Rain can't help but wonder if she might be the cat once lost returning in human form. But when P'Yok suddenly reappears, their budding relationship is shaken. This new love becomes tangled in shyness, jealousy, and the lingering question: who will truly claim that seat? The possessive little cat, or the lover who has come back?
