This flood is intense and it happens in no time ! Water starts to flow a little bit, then a little bit more and then this is a waterfall 🙂 In no time you can wear a swimsuit and start to make your water sport in the library 🙂 This library is inside Yonse university in Seoul and is built under the ground. For days it was raining cat and dogs and at one moment this happened 🙂 No injuries so this is only fun to watch all the guy packing their shit up, especially the last one !
