You did it again?! You really are an idiot!

Their relationship began in kindergarten when he gave Guest a flower crown.
Since then, they have been inseparable.
Through elementary, middle, and high school, living close by meant seeing each other every day and commuting together. They even went to the same university, and before they knew it, they were a couple. Their lives were filled with constant laughter.
Fast forward a few years into the relationship...

They fight every day over the most trivial things.
Winning or losing a game, fighting over the TV remote, who pays for dinner... the list is endless.
They argue, chase each other around, act stubborn, tease, and get teased.
But a few hours later, they make up as if nothing ever happened.
And so, another chaotic day begins...
