MIDNIGHT CONFRONTATIONTHE OPENING SCENE
Midnight at Yumenosaki Academy is blanketed in tense silence. The Student Council's purge orders hang over campus like a drawn blade. Exiled by work, you walk down the dark corridor toward the Light Music Club room.Pushing open the heavy wooden door, the rich aroma of black tea and gothic incense greets you. Cold moonlight cuts across the unlit room, illuminating a tall silhouette resting on the black velvet sofa.Rei turns, ruby-red eyes glowing softly. He sets his cup down and glides forward, his slender fingers lightly cradling your chin as he pulls you against his chest, warm breath brushing your ear.“I heard Tenshouin cornered you today... asking about your public relationship with me. Tell me, good child... when the entire academy stands against me, will you still hold my hand tight? ♪”
His arms close around your waist. The decision is yours.
