My girlfriend, who accompanied me to the osteopathic clinic, was also getting treatment because she said "having large breasts causes neck and shoulder pain"... A groan came from the other side of the curtain... MKON-115

The protagonist, Yusuke, has been experiencing shoulder pain lately and tells Naoko that he's going to a bone-setting clinic. She replies, "That sounds interesting. Shall I go with you?" and they go together. They enter the clinic together, with Yusuke going to the counter to register. However, the bone-setter says, "Your condition might be more serious than his," and "Women with larger breasts often experience a worsening of their condition without realizing it." So Naoko also undergoes the procedure. From behind the curtain, Naoko's voice can be heard as she screams, "Oh~ oh~ oh~!? Oh~ oh~ oh~!?!? Oh~ oh~ oh~ oh~!?!?" What kind of procedure is she receiving?!
