Happy happy happy♪

Happy Seven-Eleven day, everyone.
Did you grab some luck at Seven-Eleven today?
Me? I went to Seven-Eleven nearby yesterday, and the store manager called loudly, "Today is Natto's day," but I didn't buy it.
In addition, unfortunately, I couldn't get any luck since I didn't go there today.

That aside, during the lesson with teacher N yesterday, she shared a funny episode with me.
According to her, someone had been singing in her head like "Happy happy happy♪ Happy happy happy happy happy♪" again and again, and she shared its YouTube link.

After the class, I opened the link and listened to it.
Unbelievably, I got addicted!
Someone has been singing in my head over and over.

At the beginning of the class today, I sang it, and she laughed a lot and said, "It is LSS, Last Song Syndrome."
However, it is OK because the lyrics are "happy," not ominous.
I'm curious; until then, these lyrics and melody will remain in my mind.

That's all for today and see you around.
