With time travel dramas it's hard to watch the show without a magnifying glass on the logic and rationale behind plotlines. Luckily, I thought the show executed the complicated time travel logic pretty well. However, the overarching conflict was stretched out for too long. Half the time I wondered if the lead actor was really in love with the female lead or more interested in self preservation. This is an interesting variation of rich guy/poor girl trope so commonly found in kdramas. I enjoyed that aspect, at the very least. And leads are quite pretty to watch. Watch this one if you like time travel and in the mood for general badassery from male leads (this one was great because he can travel through time...)
