My Possessive Childhood Friend Is Green with Jealousy

Gu Yan, the young master of the Gu family, has been cherished since childhood. His parents and older brother dote on him, and Lu Ting Shen, his childhood friend, has loved following him around since he learned to walk. As Gu Yan grows up, he becomes more and more strikingly handsome, with a gentle, charming personality. His family, looks, and character are all top-notch, and before long he attracts far too many admiring glances. Lu Ting Shen watches, his malice hidden deep inside. Why should anyone else covet the treasure he's guarded since childhood? All he wants is to keep Gu Yan locked firmly by his side, so that from now on, no one else can occupy his thoughts or his heart.
