We first met when we was in grade 4 when i saw him i think he's a typical nerd at that time basically he's not my type we had a first conversation when he is the one whose checking my test paper he said my score is pretty ..... pretty low hahah then i don't remember but we became good friends,then it was our first time to see each other in the mall(this is not a date basically) were pretty young at that time im only 10 y/o so as he we have something to buy in there dealing with our project and when i see him in his hoodie it was a slow mo as he comes nearby to me that the first time i felt that thing i don't no what is that feeling back then to felt with that in a guy
Then we became classmate in grade 5 and grade 6 that time he had her first girl friend so as me but he was first then, i don't know but in my eyes he is getting hotter i don't know if it was just me but i think i like him a lot, and we became seat mates were very close to each others body that time im so sure that he is straight but all of a sudden he place his hand in my legs he look at me and smiled and i smiled back then his hand is getting closer to my (you know) but for me is nothing bcoz i dont understand whats happening with us but as he get closer he rubbed hes hand in my crotch the i looked at him and he is smiling, but i liked it though i dont want him to know end then i say to him dude that class is about to start,
