OMG YOU ARE SO CUUUUTE AND SWEET, AND WE ALL KNOW THAT .... but I will still ship her with the other male lead. I like it when MC gets over his attraction by spending time with another. For me, that's the real meaning to love. At first, you just brush the person, not caring much or even hating that person at first, but as the time passes by you find the way that person smiles sweet, you like his mimics, the way he speaks, thinks and without noticing you fall in love.
I am hoping this what will happen, even tho the fact that her "first love" will love her back because she is such a sweetheart is cute as well, but it doesn't show how much the MC evolves emotionally.
