God has sent everyone in pairs, it is just that you haven't found your match yet and this story is exactly that. Two visually challenged people meet at a photography club, fighting their own demons. They both are sensitive to receiving help from others.
Being an observer I can say they might feel a bit defensive as to many people are not helpful when in need. Also, those helping out might be dangerous too. But there are good people too who genuinely help people. but don't judge others who don't want to receive help, respect them. we don't know what they have gone through.
we also see many other characters and how they speak up about their life positively. It brings joy to see that this world has hope in various ways.

Watching this 30min movie gives a calm relaxing feeling just like watching a sunset on the beach. It also motivates me to help others who are deprived in some way. God has given me a healthy body and I should be grateful to for it.

Han Ji Min acted with her eyes and its brilliant.
Park Hyung Sik is excellent too spreading his charms.
