Mellow in May (2012)

Han Oh-Wol (Jo An) meets Dong-Hoon (Ki Tae-Young) for the second time on a rail line scheduled to shut down soon. They fall in love. They agree to meet at a temple 2 years later, but Dong-Hoon disappears after leaving a chair he made for Han Oh-Wol. On the day of the last train, O-Wol leaves a voice message to Dong-Hoon.
