>>4317135Choosing A is selfish because you both deny your oshi her dreams, you also deny others the joys of her talent.
Choosing B shows that you don't have faith in your oshi, as you feel like you have to give her the dream she's looking for.
Choosing C suggests that you are a controlling person because you assume that because fellow oshifags love your oshi romantically. If they aren't compatible, you have just caused a slew of heartaches and divorces.
It is a tough choice, though if I had to choose, option C seems like the best due to maxmising the happiness around the world.
