Green Plum Island 

When I was ten, I fell from a tree and hit my head. After I woke up, my world had changed. I could see people's emotions. The mood values appear visually, and are even color coded. Pink is love and red is anger. Green means embarrassment and blue, sadness. Yellow signifies lust… During my summer break, I met Yan Kongshan, a guy nine years older than me, on Green Plum Island. The enigmatic, handsome, and somewhat pensive hottie was the object of desire for all girls on the island. I felt the same, so I wanted his emotions to turn pink for me... But they became yellow instead. Even with that above his head, there wasn't the slightest change in his expression. (Source: Bilibili Comics) Note: Chapter count includes 10 extras.
