I really enjoyed watching this, it was a really sad and heartwarming story. You feel sad about what happened to Seo Ri. Especially after being in a coma for 13 yrs. When you experience her journey of her trying to get her life together after that tragic car accident you also witness the other people who were also frozen in time as she was but they weren't so fortunate to be in a coma as she was. She remained innocent and pure which could be a blessing and curse due to the fact she was asleep for 13 yrs while the other people she met who were affected by this tragic accident suffered severe ptsd. They all didn't know they were connected by this one tragic event, Seo Ri unbeknownst herself after waking up from her coma started to heal the people she lived with to be awake and live with the trauma of the outcome of the accident. Her pureness of still being a child mentally and emotionally started to heal Woo Jin and Jennifer who were victims as well of the tragic car accident only by knowing the people who were direct victims suffered from severe ptsd. Seo Ri helped them learn how to love again and helped them heal while they were frozen in time. They felt like they had to protect Seo Ri cuz she was so childlike they couldn't help but feel like they had to be there for her. She was still mentally a 17 yr old when she woke up cuz that's how old she was when she went into her coma. When she finally did wake up she was 30. Seo Ri had a really hard time coming to terms with the fact she was no longer a child but an adult when to her the accident was recent and not that 13 yrs had passed. So you get to witness that which makes you sad but you feel how everyone grows to love sweet and innocent Seo Ri you feel the love that follows her. Even Woo Jin's nephew who is 17 seems to be wise for his age for someone who isn't so bright. I think he had to grow up when he saw his uncle having severe depression and made 6 yr old Chan grow up. So even if Chan didn't know it, he was also an indirect victim of the same car accident cuz he grew up witnessing his teenage uncle fall into a deep deep depression cuz his uncle blamed himself for Seo Ri's accident. Chan managed to convince Woo Jin to Seo Ri stay with them so she can be able to get on her feet and find her family cuz when she woke up she was all alone. You will really enjoy the ending too it was such a good ending. The only thing I couldn't stop thinking about was very minor plot holes cuz even tho Seo Ri was asleep for 13 yrs and didn't know how to use smartphones cuz they didn't exist the way we know them now when she went into a come around 2005 and the modern smartphone that we know it know came out in 2007/08 like iPhone and android, she still knew how to use the computer and the internet. She asked Chan to use the internet and looked confused at Chan handed her an android phone, so when she started to use a laptop they had she used the internet, I can't fully remember what exactly she looked for online but what kept bothering me is that she never once looked up to see where her family was or her friends. If she did look up family I don't remember but I kept saying if she knew how to use the internet why wasn't she searching for her family and friends you would see Woo Jin constantly looking up information on Seo Ri's family and friends but never saying anything until near the end of the drama. I think the reason why she never bothered to check cuz the nurses at the hospital she stayed at lied to her for her recovery but it still bothered me that she never even tried to see where they could be. Like even not to go directly to her High School to meet up with old teachers but I guess the writers didn't think it was necessary to the plot. So that's why I brought up it's just a me thing. Anyways I hope you enjoy/ed the drama as much as I did it was super cute and I hope I can find another drama similar to this cuz I left feeling really satisfied with the entire story which is rare for me.
