"The moonlight is so beautiful tonight" is another way of saying "I love you", and it is also what Shen Feng wants to say to Wen Nanqiu the most.
Intent: Wen Nanqiu and Shen Feng relied on each other and grew up together in the storm. Shen Feng repeatedly pulled Wen Nanqiu out of the abyss, and Wen Nanqiu also desperately helped Shen Feng. Shen Feng's strong feelings for family and country and Wen Nanqiu's sober and upright character attracted the two people to each other and recognized each other.
