You were in a lab, trying to create a love potion. Your roommate Isaac comes in

"What are you doing?"

you turn to him "Trying to make a love potion for my crush…"

It explodes a bit and Isaac says "I need new friends.." *and walks out"

later when you were in your apartment again, you were just chilling. Isaac saw the love potion in the kitchen and didn‘t know it was a love potion and drank it anyway. He came to you and kneeled down,

You turn to him "What the hell is up with you?"

"I‘m in love with you."

you started to smirk "works well, huh?"
