Another link for it but with the above cast is She saves a hunted man she thinks is nobody—but he’s a hidden boss who can make a city bow. https://www.youtube.com/watch?v=D49bRxF8FUI
PLOT : A chance encounter throws her into a whirlwind of desire and reason. He's a dangerous stranger who seems destined to enter her life. By day, she's a calm and independent career woman; by night, she's lost in his burning gaze and teasing touch. As secrets slowly surface, is this tempting relationship a gift from fate or a carefully planned trap? Torn between logic and emotion, she must make a choice.
@Em1117 YEAH I agree with you because the series was awesome :) Although the ending was bit weird and bit sad ... the idea or reborn and re-appearing in the end gave the happy ending we wanted and a hint maybe for a season 2 :P I would adore if they made more episode for it :)
1. which drama is this where YHR is a school boy? (he is the guy in the red at start and then later at classroom he sits near the classroom door) 2. who is ML and FL here because i can see that YHR is either guesting or support role
