Since this a web drama (most web dramas usually don't take more than an hour each an episode) You can watch this anytime. You can watch this in only a short amount of time....
By traveling back in time, she realized how hard it was for her mom. She made a lot of hard decision to make the future (or present) right. By watching this web drama, I learned that we should understand our parents because we do not know what they had been through. Even though I had to wait for the next episode for so longgg (like every 7 days), it was worth the wait. Anyway it is a really nice story I give it a 10/10.
