Like Thunder from a Clear Sky

Riko Imai is good at studying, but when it comes to life, she is a true negative person! She simply cannot communicate with people, which is why she has a total of zero friends!
Takakura Karin is pretty, but simple as a five-cent coin: she lives without worries, never thinks before saying something, and as a result, sometimes brings discontent upon herself from her peers.
And one day, by the magic of a storm, two such radically different girls... Swap bodies?!
This is a story about how to find, accept, and love your one and only "self" in this complicated and sometimes cruel world!
