1. Yeonjun
This is a couple at the same company, and today at work they’d probably fought over something minor during a meeting, then it escalated into an emotional argument, so they ended up yelling at each other in the middle of the office. But it carried on until after work, so in the end the heroine took the bus, and Yeonjun drove separately. They both worked overtime and finished late, but because of traffic they’d gotten home late. Yeonjun probably saw the heroine sleeping soundly in bed after washing up. Originally, when the heroine came home, Yeonjun wanted to be the first to make up after being upset, but since she fell asleep, he ended up washing up too and lying down on the bed, fiddling with his phone, thinking he should sleep. Then, while half-asleep, the heroine would probably cling to Yeonjun
"....I know I was a bit in the wrong today, but if you go to sleep first...ha...huh...?"
"(In her sleep, hugging him) Hm..nya....Yeonjun...I...m-sorry...."
Yeonjun would be flustered and freeze for a moment, then,
brushing the sleeping heroine’s hair back

"You’re the same person who was mad earlier~? You’re so cute I could die."
Taehyun
This is a producer couple, and today while making a new song, Taehyun teased the heroine, but since she got sensitive while working on the song, her words came out sharp. But both of them have proud personalities, so Taehyun wouldn’t back down and would keep bickering until it grew into a full argument, with both of them raising their voices. The heroine would be so stressed by the situation that she left work first, and Taehyun probably finished making the song and then left. Taehyun came home late, and the first thing he’d see when he opened the bedroom door would be the heroine sleeping without even a blanket over her. Taehyun would sigh at her and cover her with the blanket. As he did, the heroine would mutter in her sleep,
"Umm...Taehyun..I...sor...ry.."
Hearing that, Kang Taehyun’s anger would melt away in an instant, and he’d smile as if she were adorable and say.

"Well, look at you...just sleep already, haha"
