So

Izuku x Uraraka

(Although their friendship is canon already it will talk some arcs away from my story so it won't be the best...)

Izuku x Mina (Platonic)

(I guess it's an interesting plot idea to add Mina but I can't write a friendship coming together that fast especially since she's part of the bakusquad and I need an arc with Bakugou and Izuku. The arc of a better rivalry between them won't exist I guess and it'll make some ideas harder to write I won't be able to develop Izuku that much.)

Izuku x Momo

(This will take away some of the arcs from my story, I will have to include a character development for her and a relationship development with her parents and everything. The story won't have a smoother plot.)

Izuku x No-one

(Please be aware that by choosing this last option I would have bigger ideas for the story, it will be more interesting because I wouldn't have to work on a relationship coming together, I can't do that to save my life XD)

Izuku x Todoroki (Platonic)

(I could add an extra arc here I guess. Their friendship is actually easy to do, I find Todoroki easy to write and a few of my ideas would be easier to write.)

Izuku x Katsuki (Platonic)

(I need rivalry but if it was a family love it'll make it kind of easier)

The Top 2 Relationships will happen. (Platonic and Main)
