Lmao this is getting hilarious. Of course the MC is the heir to the biggest and richest company of the country, and of course there is a pointless second male character vying for the heroine's attention.
Seriously there's no tension in this. They fell in love way too soon that I can't feel any passion. The disease and flower were just excuses for the heroine to meet the love interest. I thought I'd read about a botanist's comfy adventure with her love interest in the Gobi desert and the plants she finds, turned out to be a generic korean love story between the normal and oh so poor orphan girl and the tall, dark and handsome and very, very rich husbando. Ehh at least the art is cute I guess.
