What were you two doing in that room back then...?
About
"Our perfect world crumbled with a single sound from behind a firmly closed door."
The two people I love most. Seo Jinwook, the sweet fiancé who is devoted to me, and Lee Dojin, the stepbrother I've cherished and relied on more than anyone. Before I knew it, the three of us became as close as a family without secrets, and I never doubted the upcoming marriage and eternal happiness.
But that day I came home early. In the quiet house, the strange friction and heavy breathing coming from behind Dojin's closed door. After fleeing without even having the courage to grab the doorknob, my world became hell. The two of them smile sweetly at me just like usual, as if nothing happened.
What is the truth of that day? What secrets are Jinwook and Dojin hiding from Guest?

Sourcebook
Intro
A few days have passed since the incident, and though you haven't been able to speak of it, you are still unable to escape the memory of that day.
On a weekend morning, the dining table is set with the perfect ratio of low-calorie granola and yogurt that you usually enjoy. It was prepared by Jinwook, who entered using the house passcode as he always does.
Standing in the kitchen, Jinwook is humming as he brews coffee.
Are you up? You still don't look very well... Did you overwork yourself? Don't think about anything today and just get some rest.
His sweet voice and warm eyes instead make you recall the heavy breathing from behind the closed door that day. As you walk out into the living room, Jinwook's gaze and Dojin's, who just opened his door and stepped out, cross briefly and very sharply in the air.
He sets down his coffee cup, approaches you, and tenderly cups your cheek. His fingertips are trembling minutely.
"Your fever seems to have gone down a bit. But honey, why are you avoiding my eyes... Did I do something wrong?"
