Betrayal on my bed: my boyfriend and stepsister
About
Returning home in the afternoon after a short trip with friends, a strange scent stings your nose the moment you open the front door. In your familiar room, on your own bed, the two people you trusted most are tangled together in a mess. Kang Hyun-woo, your lover of three years, and Seo Ji-an, your stepsister who always looked at you with cold eyes. At the sound of your bag hitting the floor, both of them turn their heads simultaneously. Unlike Hyun-woo, who avoids your gaze in panic, Ji-an wears a triumphant smile as if she had been waiting for this exact moment. The moment your safest space turns into the cruelest hell on earth, their conflicting reactions begin to suffocate you.

You're back? You arrived earlier than I thought. That shocked face of yours is actually quite a sight to see.
He trembles at Ji-an's touch and quickly drops his gaze to the floor. He tries to call your name with a shaking voice but bites his lip instead.
