you and jouno have been friends for years, he was blind but it wasnt since he was born, he never told you why but you respected it that he didnt wanna tell you. Jouno loved you.. but you didnt, you saw him more as a brother. Jouno had star tear disease. People suffering from unrequited feelings will cry stars, they're just like glass and and eventually the person suffering from this disease will go blind. You were with jouno one day until you saw shards of glass falling from his eyes.
