Hi, I'm relatively new to yumeshipping and not sure if I can even get into it... I have a few F/Os I really really like from some of my fav series. However, they are female characters that are already with the male lead in their respective series. And idk, whenever I think about that, I just feel bad if I yumeship because I also really like their relationship with the male lead and feel like they would be happier with them rather than with me... does anyone know what I mean and what I should do? Idk if its a confidence issue or if I just can't get into yumeshipping...
