I Switched to Archaeology, and Boiled Two Rice Dumplings on the First Day of School

I'm just an ordinary archaeology enthusiast, but after helping my grandpa deliver a “package,” I nearly ended up dead. A weasel getting married by moonlight, a peony speaking in a human voice, a koi fish coming back to life in the river... Are these really things a young man of science should be seeing? What? A parade of ghosts? There's no way I'm missing out on that!
