Wit's manga / #pianist(2)

A guy working on a farm in australia while he takes time off of college meets a man who's playing the piano at a dinner party. As payment for becoming an uninvited audience, he must pay by sleeping with the pianist (and he finds he loves it!). However, after he runs far away back to korea, turns out he goes to school with the guy. And their fuck buddy relationship is not yet over

Sure piano is how they communicate but these two boys are absolutely obsessed with each other
