Clubsweethearts 24 09 14 - Iris Murai Needs Her C

Let me outline a possible plot: Iris is in a club (maybe a tea or flower arranging club, given the name). She's introverted and struggles to come out of her shell. The "C" could be a nickname, like "Courage" or a character, like a boy named Charlie who pushes her to open up. The story follows her growth from shy to confident, culminating in a romantic development with the love interest.
