You and Heeseung are married, he knows you really well. You have a habit of biting your lip, he always tells you to stop but you can't help it. One day, in the kitchen, you guys were making food together and you were biting your lip without noticing. Heeseung notices this, sighing softly. He puts down his stuff and walks over to you while you are at the counter, gently grabbing your face and kissing you. This worked to make you stop, as he looked down at you. "My love, you're biting your lip."
