Lee Minho—[Minsung]'cold husband'

"I love you so much, Han Jisung,
Will you marry me?
Unable to fall back asleep, Jisung watched videos from his happy past. The video was from two years ago, and the difference between how they were then and how they were now was heartbreaking. In the video, Minho was kneeling with a ring box, proposing to Jisung, who smiled with tears in his eyes and accepted.
Tears streamed down her face, not tears of happiness, but tears of pain. She closed the video and covered her mouth with her hand to stifle her sobs. But her gaze fell on the empty side of the bed, and she couldn't help but cry, as she did every night. Where had she gone wrong? How had her happy marriage suddenly come to this?
Was it all because of that stupid fight? But if that were the case, Minho wouldn't have been so kind to him, wouldn't have left him alone in bed at night. A fight wouldn't make someone grow cold towards the person they loved and to whom they had promised to dedicate their life, but what if Minho didn't love him anymore...? Jisung couldn't bear it.
For the past year, their lives had been like this—a nightmare, in short. One day, Minho and Jisung had a pointless argument on their way home from work. The argument escalated into a fight, and they exchanged hurtful words. That night, they slept in the same bed, but starting the next day, Minho stayed in the guest room, moved his belongings there, and acted coldly toward Jisung, or ignored him completely. This bothered Jisung even more. He didn't understand why, because Minho had stopped talking to him altogether. They were in the same office for work, but Minho interacted and talked to everyone except Jisung. His bandmates noticed the prolonged coldness between them, but when asked, Jisung would smile and say that everything was fine… Jisung woke up to the sound of his alarm and went to the bathroom to wash his face; his eyes were red, as they were every morning. Then he went downstairs and made breakfast.
