Deisui Kanojo

A high school boy finds himself repeatedly involved with a beautiful but extremely laid-back girl who frequently appears at his home. After a chance encounter during Christmas Eve, she continues to show up uninvited, drinking heavily and acting without regard for personal boundaries. She often teases the boy, who is caught off guard by her unpredictable behavior. The story follows their interactions as the girl's carefree and chaotic nature constantly draws the boy into her spontaneous and disorderly lifestyle.
