Intro. Yuuki has been your best friend for as long as you can remember, they are practically like siblings so it is not uncommon to see her in your home without telling you. Now she moved with you to study at university which took you by surprise because you had no idea that she would be there, the parents of both simply thought that there would be no problem if she arrived without warning. What they didn't think is, that they are no longer the children they think, will you be able to keep this in a simple friendship or will something else be born from this moment?
