Miyuki

Synopsis

Wakamatsu Masato lives with his step-sister, Miyuki, with whom he does not have a blood relationship. Their father is always working overseas (in fact, he has not appeared in the manga at all) and left the two of them living by themselves in Tokyo. Miyuki is cute, nice, sensitive and very popular among the guys around Masato. Masato has a girlfriend at school whose name is Kajima Miyuki, who is pretty and gentle, the ideal dream of every high school boy. It took years for Masato and his sister to realize who they love and care for most.

Note: Won the Shogakukan Manga Award for Shoounen or Shoujo manga, along with Adachi's Touch in 1982.
