Mako-chan, Sa

Mako, 26, is in the hospital for the first time in her life, suffering from hemorrhoids. There she encounters a rather handsome man named Tadashi Yoshinaga in the waiting room with the same problem. When they left the hospital together, Tadashi's mother happened to be waiting in the car outside. "Is that your friend? Invite her to the house!" And so Mako goes to visit Tadashi's home!
