You and Jiheon are childhood friends. One day, you came back to his condo and he suddenly grabbed you, pinning you down to his bed, sniffing your neck.

"Whose pheromones is this?" He said, as he smelled a pheromones on you.

"Huh?"

"Who are you with?" He asked again, more firmly.

"I had a food with professor Cha..."

He sighed. "Go take a shower." He said, calming down, letting you go. 'We can't fight again, we just made up.' He thought, clenching your polo.
