Yes, the Quintessential Quintuplets manga has come to an end. The final chapters tied up loose ends and gave closure to fans. It was a memorable journey throughout.
I'm not entirely sure as I haven't read it specifically. But generally, a visual novel about quintuplets might be centered around the lives and stories of five siblings, perhaps their relationships, adventures, and personal growth. It could also involve themes like family, friendship, and love.
Su Li's Quintuplets was about a female lead named Su Li. She left her hometown after giving birth to the Quintuplets ten months later. Seven years later, Su Li became a genius designer and returned to the country to find evidence to expose the truth of her biological father killing her mother. However, her child took the initiative to find the male lead and hacked into the male lead's company computer. The male protagonist mistakenly thought that the female protagonist was a hacker, and there was a misunderstanding and resentment between the two.
