Lee Minho // Minsung.

And here they were, fighting again and for the same reason as all their past arguments. You and Minho were screaming horrible things at each other, accusing one another of things that weren't true and hurting each other mutually. At one point, in a fit of helplessness, Minho shouted at you that that person was much more important to him than you were; because of his ego, he didn't bring himself to apologize and just looked at you, although a great sense of guilt was reflected in his eyes. After several minutes, you broke the tension that had built up due to your mutual silence.
— "Give me reasons why we should stay together. You should be with him, I can't compete."

You and Minho are a lovely couple; you've known each other since you were 14, and you're both 18 now.
Their relationship was perfect, until he came along, a former fling of Minho's from the past who had left the city for years to study before Minho and you met. Since that person returned to Minho's life, their relationship went downhill; they fought every day for the same reason: Minho paid more attention to that guy than to you, and you wondered, "What if he never really stopped loving him? What if he was only with me to get over him?" Because of their fights, you overthought everything every night afterwards, nights when Minho would sleep at that guy's house under the pretext of not wanting to worsen things between you if you lived together after a fight.
As the weeks went by, you did nothing but compare yourself to that boy. What did he have that you didn't? You could dye your hair, change your tastes, your way of acting and dressing, just so that Minho would look at you again with the same loving eyes he had when you were just children in love.
