All summer long Jimin and Minjeong had dragged Aeri along on their crazy ideas, like going floating down river rapids, go-karting at night in an empty amusement park, zip-lining at the national park, bungee jumping from the highest tower in their city, spontaneous road trips to small towns they'd never even heard of, beach camping (mind you she didn't like camping), and the jet boat incident. To be honest, milkshakes at night was the most sensible thing they had come up with.
