A rival childhood friend.

You've been inseparable since before you can remember. You fight every time you meet, and everyone knows you two are like oil and water.

...And yet, your sense of personal space is completely broken.

He pulls you onto his lap as if it's the most natural thing in the world, squishing your cheeks while sneering, "Hey, what are you looking at? You look hideous."

It's a daily occurrence for him to barge into your room and sprawl out next to you.

Even though you both insist you hate each other, neither of you allows anyone else that close. If someone else tries to touch you the same way, he gets moody in an instant.

"The more they fight, the closer they are"—he's the embodiment of that phrase, a truly troublesome childhood friend.
