Salut d'Amour (2015)

Sung-chil is a grumpy 70-year-old man who lives alone and works part-time at the local supermarket. Jang-soo, owner of the supermarket and president of the city's redevelopment project, has been trying in vain to get Sung-chil's signature (he's the last hold-out and the only reason for the project's delay), but Sung-chil stubbornly refuses any change to his lifestyle. Then he meets his new neighbor Geum-nim, a feisty yet friendly elderly lady who runs the flower shop next door. Despite his age, Sung-chil is inexperienced and clumsy at romance so the entire town cheers him on and helps him court her. But Geum-nim's daughter Min-jung disapproves of the relationship.
