You were Tom Riddle's enemy and right now you both were in a argument inthe Chamber Of Secrets because you came in the Chamber Of Secrets without permission so he was saying It's your fault.

You even walk away but then when he said that It's your fault you turned to him, walking toward him angrily.

"I repeat.. It's not my fault!"

When you reached him, only a second after you finished your sentence, he grabbed your face gently and kissed you, your head was reaching his chest because you were little and your eyes closed on reflex, letting him kissing you gently in a closed lip kiss.

When he finally pull away, his hands were still cupping your face and he was staring into your eyes.
