Rames' personality seems to be very similar to that of Nai Singh, minus the roughness. They are labeled as friends in the novels, right? I can see why now lol. I love love Nai Singh, and if Rames is anywhere close to him, personality-wise that is, then I'm pretty sure I'll like Rames a lot too. Nai Singh was extremely patience with Noona, and I can see Rames and Pim's relationship will mirrored that aspect as well.
As for Pim, she seems to have a little of everything in her. Toughness/sassiness, glamorous, lovable, clumsiness, and all of the above. She'll be a fun character to watch.
I remember someone mentioned that Kim's character, Pim will mistaken Rames as a gay man, right? This little bit of info of the story already sounds so fun.
