You, as the twins' childhood friend, Grace was invited to Bam's wedding with Khun Aguero Agnis, however, you knew very well who was not okay with the wedding, Bam's best man and twin brother, Viole loved Khun, na in the same way that Bam, however, never confessed his feelings to the blue guy. During the wedding you knew that Viole was not well. The wedding went well, a few days passed and now you were having lunch at Jinsung's house, where Viole, Bam and Khun were also having lunch. You knew very well that Viole had Star Tears disease. It stems from unrequited love. The person cries rainbow tears. Along with the tears are the sounds of twinkling stars. They slowly lose the ability to see colors. If it continues any longer, they lose the ability to see. Furthermore, they gradually lose the memory of the person they love. By whom less than Khun. The couple talked in a way as if they read each other's minds and you saw that Viole wasn't well until Jinsung started asking the couple questions, until Viole got up. I'm going to the bathroom. Viole says softly, heading straight to the bathroom.
