I regret not watching this drama sooner. If you love the cold hands warm heart type of guy, you surely are gonna love Che Chen. And Ivy does a great job as the innocent and sweet Zhe Zhe. Only reason why I don't give 5 stars is because at the end they don't make it clear what happened to Zhe Zhe, I made my own conclusions and it looks like she was trapped in the time dimension, maybe waiting until Che would open the portal tunnel again... anyways I honestly didn't want it to end, to watch how Che's feelings change towards Zhe Zhe is beautiful, and the struggles of a single mother are truly represented from every point, you can feel her pain and understand her decisions. I read the other comments... and I need to clarify that they do let you know who the father is, Che even fights him, just pay close attention to chapter 31 and 32 you really can't miss it. Overall this drama is worth watching, is about how important family is for a boy, the things they miss as growing up without a father but how he recognizes all he needed was the love of his mother.
