I need a iced caffe latte, especially in hot summer

This summer is too hot. Seoul's temperature reached almost 40 degree.
I can't believe it. It seems like I'm in East-south Asia.
(when Korean talking about hot weather, we usually use word "East-south Asia".)

I don't like coffee, because of it's high caffeine. when I drink coffee, I couldn't sleep well at night time. and I'll be too sensitive directly after I drink coffee.

but this year, I don't know why I am enjoying cafe latte.
Recipe is very simple. just prepare iced soy milk and add instant coffee. that's all.

I'm changing. like... I didn't like sweet red bean or sa-si-mi before, but now I like it.
