The continuation of Kao, Pete, Sun and Mork's story.
Kao and Pete being in a blissful romance, have grown closer. But with Kao being closeted from his mother, he fears the dreaded thought of her finding out. His mother then introduces Non, a son of a colleague, as he requires tutoring from Kao. With Non constantly giving off 'iffy' vibes towards Kao, it only fuels Pete's jealousy. Their relationship is put in strain, but through this, they must ultimately overcome each other's flaws. They both blossom in their youthfulness coated by their everlasting fondness for one another. Surrounded by the wonder of dark blue, Pete and Kao surrender to their feelings.
Sun starts taking hints from his unrequited love and slowly gives up on Kao. Through this Mork happened to possibly comfort him. Whilst Sun pushes Rain to stay away from Mork, the younger man's uncontrollable behaviour brings him in. As his wildness is intriguing, Sun's seriousness holds Mork down somewhat. Underneath it all, the two start to care for each other. However, with Mork's dangerous life, he can't shake who he is. But maybe he can for someone like Sun.
A twist, where our lead girl is the mean girl.
Thae is a spoiled rich girl and very demanding to Pittiya who works at her father’s company. He also happens to be an adopted son, therefore lowly status in Thae’s eyes and worthy of bullying. She feels she can tell him to do anything and he must obey. Pitt on the other hand, despite inevitably obeying her orders, he doesn’t do so without a fight. He never gives in to her emotional, flighty ways, which pisses her off to no end. Pit gives in to her out of respect for his adopted father, but he would much rather dance attendance to Ravee, his girlfriend. Because of his girlfriend, Pittiya rejects the offer of marriage from Thae's father. Thae can't believe he refused her and plans her revenge. She tries to break up Pit's romance by pretending she and Pit have a closer relationship. But why all the hostility towards Pitt?
