sende benim icin olesin

onun icin diyorum sana tek tanem diye

for me you are the same too; I am telling you this because you are my only one

Thank you so much for your kind help.

 Or it could be :"That is why I call you my one and only".

e.g. My mum made great apple pie.

You are the same

That is why I call you my one and only

Need the context to decide!
