I liked a lot of the characters and they seemed to have good chemistry with each other. The show did a good job of conveying a warm vibe. However, the plot had so many holes that were left uncovered that I couldn't believe the last episode was actually the last one. Here are my questions- Why did he call her Irene? Why did he engrave goodnight on her keychain? If he awaits her arrival every winter and has been in love with her forever why did he decide to suddenly be more proactive this particular winter? Why did he so aggressively reject her when she told him she liked him? Why didn't she ask any questions after he kissed her- it literally came out of nowhere and seemingly contradicted all his behavior to that point? What happened to his uncle/ his plan to leave, start a new bookstore? Why didn't she even consider maintaining the relationship before leaving town? Why did he have no dreams in high school and how did he get more positive/ warmer despite going through worse with time? What was the deal with his mom? She loved him but left him but came back but then required his care for 3 years before dying then haunting him? What actually happened to his dad? They got all weird when his uncle came to town saying maybe it's his dad... Why don't the lead couple make plans together? What's this about them dating only while she's in town which is completely random? Why doesn't she stay or he move? Why doesn't he visit her? Seoul isn't far?! Who reads his blog? Why is he so secretive about it with her even after they're together? Make. It. Make. Sense.
