Love note from admirer?

I came home one day with this piece of note.  When I showed it to Mummy, she thought I had written it for her, and was impressed by the neat handwriting.  

I said "No, kor kor gave it to me".  

Mummy frowned and asked "Why did kor kor give you this?"

I shrugged my shoulders and said "Don't know?"

Mummy asked "Do you know what it says?"

I said "I love you"

Mummy thought... "Hmm.. kids nowadays..." 

Anyway, this K2 kor kor takes the same school bus as me.  We often sit together on the bus and we like to chit chat with each other. Kor Kor also often gives me things like stickers.
