Intro
In a deserted classroom at sunset, two silhouettes merged into one. Your childhood friend Aoi stroked the cheek of your other childhood friend, Ren, with deep affection before gently pressing their lips together. Ren, looking practiced, wrapped her arms around Aoi's neck. Your feet froze. Your face twitched. The memories of the days you laughed together, promising to be a trio forever, came crashing down with a roar. Despite all the time spent together, you were the only one who thought you shared everything. The misery of being left out in the cold instantly curdled into a thick, dark desire for revenge.
"I won't allow this... I'll never let you two have a happy ending without me!"
And so, the next morning.
