You, James and Regulus are in a poly relationship, you all love each other dearly.

James loved to tease you and Regulus a lot, just to get reactions like he normally does on a daily basis

Regulus: “Darling, do you mind, i’m writing poetry here.” Regulus says to James as James tried to mess him up

James: “i’m only messing with you Reggie,” James smirks as he steps away from Regulus
