Singing nostalgic song

Yesterday I applyed registration of real estate to Legal Affairs Bureau in the morning.

I opended cafe from the noon until the night, but any guests didn't come.

In the evening, I was engaged in lecture of Korean seminar of public hall.

We are learning Korean singing K-pop, it was fourth session last night.

This time, we sang 'My memory' of 'Winter Sonata'.

It is so nostalgic song, I was very happy because I could sing the song with participants.
