For five days while her parents were away on a trip, I was left to take care of my childhood friend Sana Mashiro. She always acts cold and distant, yet she sneaks into my bed claiming she's afraid to sleep alone, and even joins me in the bath saying she's scared and embarrassed to go by herself—wearing her school swimsuit the whole time—which leaves me chuckling in disbelief. Despite her feisty, arrogant personality, there's something oddly endearing about her behavior, and I find myself constantly flustered by her every day. Could her tsundere attitude—acting standoffish while secretly initiating intimate acts—be a sign of hidden affection? Experience the full POV footage of this cohabitation life with a sharp-tongued yet secretly passionate girl!
