Simple, beautifully narrated story with actors that played their roles believably and so, so well. It doesn't romanticize BL and treats it realistically, and the red balloon metaphor wraps up the story with an artistic touch. The female roles are also realistic in not being extremely annoying and being people that you can emphasize with. Everything felt so natural and authentic!!
The music is PERFECT-- every time I listen to the soundtrack I swear I can see the scenes playing out in front of me. Would rewatch again!
