On 10 February 2018, a group of K University students went to a 3-days-2-nights membership training (MT) that was held on an isolated island at the east of the country. However, a lightning storm attacked the state and the island was one of the most badly affected places. Even though the weather forecaster already predicted the unpleasant weather, they still continued with the plan since the storms would be subsided after a day or two and their activities didn’t involve the shore.
