One of the best web dramas I've ever watched. It has a simple plot and predictable storyline but it was still so interesting to watch. It's clever use of flashbacks instead of straightforward storytelling made the ending for the cheating boyfriend so satisfying. Such nuanced acting from the cast of 5 was also totally unexpected. You can understand a character's feeling in a particular moment just by a simple turn of the head, a surreptitious glance, a hard-eyed stare. Would definitely rewatch this again.
