Harry
You met on your first day at Hogwarts, you were on the Hogwarts Express and couldn't find any compartment which was empty, you walked down a few carriages until you found one with only one other person in.
"Hi, I'm Y/N. Do you mind if I sit here? Everywhere else is full?"
"Please... take a seat"
"Thank you, I didn't catch your name"
"Harry. Harry Potter. It's nice to meet you"
"It's nice to meet you too... Potter"Ron
You met on the quidditch team, you were in your second year at Hogwarts and were suggested for the team by Mcgonagall, when you went out on the field you were sent to the keeper who was to show you the basic steps of the game
"Umm hi I'm Y/N I'm meant to be learning the basics of this"
"Ah yes I'm Ron Weasley you will be training with me for the next week until the match"
After your first session you and Ron headed to the grand hall for lunch, you sat with the golden trio and got to know them all and found yourself in a great friendship with Ron.Draco
You met in Hogwarts, you were walking around the building trying to find somewhere to study when you accidentally bumped into something or more like someone
"I'm so sorry I wasn't paying attention"
You looked up at the person you were talking to and noticed his blonde hair and sparkling green eyes and were in a trance like state until you were pulled out of it by the boy saying
"Uh it's okay, the names Malfoy, Draco Malfoy and you are!"
"Oh sorry I'm Y/N, I really should watch where I'm walking"
"That's a beautiful name, walk with me Y/N I'd like to get to know you a bit better"
"Sure"
You spent a lot of your free time with Draco and found him to be one of your closest friendsGeorge
You were in Hogsmeade looking around for something to do when you saw a pub named the Leaky Cauldron, you went in, sat at the bar and ordered a butter beer when you heard someone at the side of you tell the bartender to put your drink on his tab and moved closer to you
"Hi beautiful I'm George, what's your name?"
"Um hi George I'm Y/N, you didn't have to do that I have my own money"
"I know I didn't have to I chose to"
You and George were having a laugh and getting to know each other and discovered you were in the same year and house at Hogwarts and formed a close bond!Fred
You met on diagon alley, you were buying your books for your third year at Hogwarts and noticed a boy next to you who looked familiar.
"Hi, I'm Y/N, I think we have transfiguration together at Hogwarts"
"Hi I thought you looked familiar I'm Fred it's nice to finally meet you"
"It's nice to meet you too, can you maybe help me find the books I need?"
"It would be my pleasure"
Fred stayed with you for the whole trip around Diagon Alley and spent most of his time with you in Hogwarts. You became best friends quickly and your bond kept getting stronger.
