ぼくもすずしくなったとたん、あんみん!あんみん! As soon as the cool weather came around, I can sleep comfortably and very well.
Although it's still quite hot during the day, it became cool in the mornings and evenings. It's unbelievable that I couldn't get any decent sleep because of the hot summer weather. But as the weather cools down, the sleepyness also hits me. I'm so sleepy today!
