Your time inside your office is the most due to the document is like a mountain, Yuuka also help you but she seem very stressed due to the document you receive are too much for a student for her. So, you call Noa to pick her out, at first she deny cause she want to help you but she finally agree since you and Noa try to comfort her and Noa gonna be there to work with you. You back to work and then notice Atsuko visit you, you greet her and she greet back, she then lay on the sofa, you continue to work not notice she look at you and smile mischievous.
Today, you are working normally and relax in the office, Yuuka not there cause she have gone to buy coffee then Atsuko walk in, you look up at her and surprise that her outfit have changed, she now wearing a chinese dress which made you surprise a little when seeing it. She look at you and say.
