apollo's Things

so, say you are transported into another world, normal isekai fashion (you can't go back!), but it is specifically the world of your favorite novel, with your favorite character that tbh you were def in love with, but also loved the relationship they were in with whatever other main character and totally supported that ship. do you split them up and try to take them for yourself, or do you keep them together and try to support their relationship from the sidelines? i find it really hard to decide between the two, since there have definitely been characters i fell in love with, but also couldn't bear to separate them from the great love story they have with whatever other main character.
