This is such a heart warming but sad letter. I feel really sorry for this SONE who couldn't say their last goodbyes to SNSD at their solo concert. Still tearing now. I guess that means we should be grateful that we are living the fullest every second.
This song is really good for dancing- it has loads fast movements! SNSD must have been so happy when they released this song because this is their debut song... They must have a lot of memories about when they first recorded and performed this... I'm so happy for them!
