Hey guys! So our school is doing a sing-a-thong (Singing marathon) to raise more money for our choir to go on tour. In the event, choir people will sing solos, duets, and trios….etc. My friend and I decided to do duets but with Korean songs since our teacher asked for more variety in language and type. We’ve decided on Akdong Musicians cover of Eyes, Nose, Lips,  and the Dream High Version of Can't I Love You by Kim SooHyun and IU .....and then we’re stuck. We need more than just two songs, but we’re not sure what else would fit with not a lot of rap in it. 
We’re really desperate to find more songs because we only have 20 days to learn it all and it’s a 24 hour event. 

We’d prefer mostly ballads or acoustic versions of songs you think are good.
Any ideas would be AWESOME. 

Do you guys have any suggestions?
