In a bush of blooming azaleas, Lee Boeun found a timid stray cat and named it Dallae. Coincidentally, on the very same day, Boeun saw Kang Seyoung for the first time and was left spellbound by her breathtaking beauty. Seyoung quickly won over hearts with her keen intellect and exceptional athleticism. Even though Boeun could not muster up the courage to utter a single word to Seyoung, she watched Seyoung with longing, observing the nuances of her charming and surprisingly mischievous personality.

For years, Dallae has been Boeun's sole confidant; Boeun shares every secret and fleeting emotion with Dallae the moment it leaps in through the window. She has accepted that the only way to see Seyoung again is through her frequent, bittersweet dreams of her loved one's gentle touches and sweetly whispered words. However, fate intervenes, and Boeun is granted another chance at approaching Seyoung. But all this time, Seyoung may have been hiding closer than Boeun realizes.
