I forgot that my plane was not leaving until evening had had basically nothing to do and no energy left. So I stayed in Hapjeong, walked around the streets and found this totally cute café: A Hello Kitty Café! 😀
One final advice before we leave Seoul together: If you see something you like, buy it. Korea has a great style and you should take that chance and buy some shoes, make up (in Myeong-dong) or, like me, jewelry.
Also, Asiana Airlines is a really good company. If it is possible, fly back home with them 😉
