DNA Says Love You

The group plans a farewell party for Ah Guan’s study abroad. At the café, Yuhe notices Amber humming a strange tune. During party games, Xiao Li asks Amber if they like someone. Amber doesn’t answer, opting to take a penalty drink instead. Lajian brings the drunk Amber home. The next morning, a tense but intimate moment lingers as they talk about their feelings.

As Xiao Li reminisces about how he and Ah Guan got together, he receives a flood of worried messages from Ah Guan. He almost calls but hesitates. Just then, Ah Guan calls out to him from behind. Meanwhile, Lajian and Yuhe are looking at old yearbooks when Amber appears. They begin asking about Amber’s time at elementary school in Taiwan...

Seeing Amber and Ah Guan together, Xiao Li gets jealous and angry. He throws Ah Guan’s book and finds an airmail letter inside—a notice of overseas acceptance. Confronting Ah Guan brings only vague answers. Frustrated, Xiao Li runs away and disappears from town, leaving friends searching desperately.

While rearranging the café, Lajian feels restless. Yuhe reminds him that Amber is just an outsider who happened to help. But when Amber appears, Lajian lights up.

Pu Lajian debates with Xiao Li at a café owned by Xie Yuhe’s brother. Their adventure video site is struggling. Xiao Li wants to fake content for views, while Lajian insists on raising quality. The argument ends unresolved. That night, Lajian’s mother suggests searching for the legendary "Gui Lai An," a dream once held by his father. Lajian approaches Xiao Li with the idea...
