She forgot everything and returned to the age of 18 but she behaved like a 13-14 years old all the time. I was expecting an actual drama but turned out to be a boring daily life of nothingness in the second half. Even if it wanted to go for a lighter rom-com route, it failed to capture that. I liked the set up and the cast but the 12 episodes in the middle lacked any meaningful structure. A bit of bad play with the amnesia part. Her memory came back way too late when it didn't even matter anymore. They had the opportunity to do a lot with what they had. At the end of the day I just want to see more main roles from Park Sun Young and even Ryu Soo Young.
