When i set two characters on page to fall in love, it's kind of an instant feeling of familiarity and of knowing someone. Characters might seem like they're exactly right for each other, and then you put them on the pase and you think, oh no, this won't work. I thought i wanted to write those one type of paring, and then this other character just kept jumping and being like, actually, in a way, more compatible with protagonist. It's exhilarating to see in characters. But sometimes the hardest part of the job is getting those characters to co operate.
