Boyfriend (SOURYO Fuyumi)

From Storm in Heaven: Takatou Masaki is the second youngest of four sons, and seemingly a delinquent by nature. His hot temper has put a wedge between himself and his strict father, gotten him kicked out of one school, and tossed him at a school notoriously horrible for the one thing he's truly good at, basketball. A chance encounter with the willful Yuuki Kanako may serve as a catalyst for change, as the indefinable connection she feels with him draws them together. Note: Won the Shogakukan Manga Award in 1988.
