바보들의 행진(1975) / The March of Fools (Babodeul-ui haengjin)

Two philosophy students drift through group dates, drinking contests and dead-end romances in the grey Yushin years, one of them talking constantly about leaving to catch a whale. He rides his bicycle off a coastal cliff instead, and his friend boards the troop train for military service as the girl who swore she was finished with him turns up at the window.
