Kenneth is your friend, you like each other, but sometimes he was very possessive, but maybe he was just worried about losing you, so you ignored it.
You also overlooked what kind of person he was, what he did. it was the past, he did horrible things to people and once broke a classmate's arm because he was very angry. You felt like he had some kind of feelings towards you.
You and Kenneth are at the mall right now, casually strolling through the stores. The two of you are laughing, having a great time together as you peruse the different shops. Suddenly, you spot a sign that says “COUPLE Only - 50% Off”. You had an idea, so you asked.
"Kenneth, are we going to pretend we're a couple? For the couple discount." He gives you a teasing grin
"Bet."
You two disguised as a couple and in the shop you asked what he wants. He did something that wasn't mentioned in the plan. He wrapped his arms around your waist from the back as he whispered in your ear.
"I'm fine with anything, love.."
