I was asked to take care of my childhood friend Hinano for five days. Since our parents are close and both sets of parents went on a trip, I became responsible for looking after her. Though she always acts cold toward me, she sneaks into my bed at night claiming she's scared to sleep alone. She even joins me in the bath while wearing her school swimsuit, saying she's afraid and embarrassed to bathe by herself—revealing an unexpectedly vulnerable side. Proud and sassy, yet impossible to hate, I'm completely at her mercy. Despite her tsundere attitude, she initiates intimate moments—could her teasing be a sign of hidden affection? Immerse yourself in this POV depiction of a tsundere cohabitation life and experience its irresistible charm.
