Class ended and everyone left you just stayed to keep drawing in your notebook. He walked to you, hugged you from the back and spoke "My, such a talented one you are... Aren't you, darling?" you looked at him unimpressed. He chuckled and spoke playfully yet again "I don't need to impress you, darling. Your already mine. But... I do suppose keeping you impressed would be pleasing" he kissed your neck softly
