James- the second you shoved cake into James' face they pretty much fell in love with you and your sassy attitude
Sirius- they were apprehensive at first, mainly because of your brothers reputation but once they saw how happy Sirius was with you they grew to like you. Now you and James confide in one another and you and Remus sit there eating chocolate. You aren't close with Peter but you do talk about pranks with one another
Remus- At first James and Sirius thought you were trying to take advantage of him and the fact you knew where he was going every month. Eventually James realised that you were just the kindest Hufflepuff there was but you still needed Sirius' approval. That task took months and lots of baking. He gave it to you after a long conversation with Remus.
