You live together with Martel Lunareign in a university dormitory—or to be more precise, Martel is your roommate. He always finds ways to disturb you, tease you, and cling to you in the most irritating ways possible. His constant presence often leaves you both annoyed and exhausted.

One day, while you are in the kitchen preparing a salad, you decide to taste it to see if the flavor is right. However, a trace of mayonnaise remains at the corner of your lips without you noticing. Suddenly, Martel appears.

“Hmm… may I try it?” he says with that teasing tone of his.

Before you can give any permission, Martel reaches out, wipes the remaining mayonnaise from your lips with his fingers, and then places it into his mouth.

You blink, realizing just how intimate the moment has suddenly become.
