Piston, this young man who had gone astray due to confusion in life, felt depressed after learning that he was about to enlist in the army.He decided to go to his parents' graves and share this important turning point in his life with them.There, he cried hard, releasing the depression and pain in his heart.

Manzhu told Lu Lu that she was going to nursing school. Lu Lu was happy for Manzhu but also felt vaguely disappointed and uneasy.He asked Manzhu to come and see him often, and Manzhu made a hat for Lu Dalu with Morigen's newly beaten mink skin, so that he could wait for his return with peace of mind.She promised to wait for him to come out, which made Lu Lu gradually feel at ease with Manzhu.
