There are 2 girls who are students, they study in the same class but different time, i think it's morning and afternoon, they sit at the same table, and girl A sees the doodle that girl B draws on the table and they start chatting by drawing or writing something on the table, then girl B gives girl A something in the desk box and then they meet at the library (I think so), this one shot has a sequel, please help me, I've been looking for a week and can't find it
