LORAE's manga / #romance(1878)

Jade Seo is a woman who has worked herself to the top from a young age entirely from her own efforts. She’s studious, kind, witty and clever. However, there’s one trip that she couldn’t remember even if she tried. When she was a child, she stayed with the Liu family in China alongside her dad. There, she developed a close friendship with a boy called Yun. But after practically twenty years of lost contact and fragments of memories, Jade is informed that Yun will be studying in Korea, and that the two will be living together!
