What should I say? 

" I don't smile at others, don't play with them as you do with me, don't do pranks on them, don't talk more to them..." He said staring into her eyes.

All she could ask was, 

" Why?" 

He closed his eyes, hugging her. 

He rested his chin on her head. 

" I don't know why! I really don't know! But I feel this way because I am afraid, you won't stay with me if you found someone better! I feel it even with Vivaan, at first I hated it when Vivaan spoke with you, all smiling. I trust him, but I am afraid again! I am possessive, I don't know why!" He said his heart out. 

" Ryan, don't be afraid of this! None can take your place, if I go away from you it would be only because of you, not because of someone! So behave yourself!" She said into his chest as he was still hugging. 

" No! Don't go away from me, even if I do something!" He whined. 

" I won't promise!" She said strictly. 

" No, promise me!" He whined.
