I shall seek you endlessly (слэш)

Right in the balcony above Zhou Zishu, there is a man with long dark hair, deep red robes, eyes as dark and bottomless as a demon’s and with enough of a murderous aura to keep everyone away. The man sees Zhou Zishu staring at him and gives him a salacious smile. Zhou Zishu feels hot all over. Heavens help him, but yes, this is exactly the kind of man Zhou Zishu would feel excited about.
