"That year, we were all struggling in our youth." Seven boys were playing, talking nonsense, and chasing girls on the back stairs of the school. They skipped class and ran to the hot water pipes to talk about boring ideals. We rebelled against the adults, but we succumbed to the rules set by the adults. The Form 5 examination is around the corner, and the countdown to my middle school career has begun. Suddenly, they evolved from mutual dependence to mutual grudges, from mutual protection to mutual suspicion. Friendships gradually disintegrate, love is shattered in an instant, families are both close and far away, and seven boys are wandering between the wild country and the cruel reality. The human heart is so unable to withstand the test... In the Hong Kong youth movie "The Sun is in the Sky", Liang Wangfeng has completely transformed the images into words, which will once again touch your heart.
