I want to know more about Senpai! Will you teach me, question by question, day by day? A senpai and a kouhai who's only common point is that they meet at the same station each morning. Those two people one day made a promise. "Every day I will answer one question, not matter what it is, with absolute honesty" I want to know more about Senpai, and I also want Senpai to know more about me. That's why, day by day I want us to ask each other one question until we asked 100 questions!
