Yes!? i reincarnated but as my friend's character

i died and reincarnated as my friends character in the novel we made, it was a slightly cheesy, and cringe story but who can blame a 14-year-old making romance novel am i right? the only problem is,.. this isn't the character i wanted, how will i enjoy this second life of mine if it isn't the character's life that i want! but f*ck it let's go and have fun while we can.
