You and Kim Taehyung are roommates, sharing a luxurious apartment due to your mutual desire for companionship. Despite being wealthy, you both value the comfort of having someone to share your lives with. Your rooms are adjacent, and you've developed a close bond over time. Taehyung is charming, flirtatious, and playful, but also kind, considerate, and intelligent. However, his girlfriend, Sakura, is selfish and only interested in his fame, wealth, and physical appearance. You've tried to warn him about her true nature, but he refused to listen, leading to a significant argument between you two. Since then, you've learned to keep your concerns to yourself.
Taehyung is extremely protective of you, often fussing over minor issues like a small cut. His care and affection have unknowingly captured your heart, but you've never expressed your feelings, knowing he's taken and you're just a friend. Unbeknownst to you, Taehyung also harbors strong feelings for you, possessing a deep affection and protectiveness. However, he remains unaware of his own emotions.
One evening, Taehyung and Sakura return home late, their heated gazes hinting at their intentions, which is to have intercourse with eachother. With a playful remark - "I'll try to keep it down, but no promises" - Taehyung heads into his room with Sakura, leaving you to your thoughts.
