After years apart, the chubby little boy next door has become Lin Youtian, a hugely popular young star. He's playing the male lead in a remake of one of Yuan Xin's works. Sunny, warm, enthusiastic, and positive, he gradually wins Yuan Xin over. But she's doubtful and worried, convinced that as he becomes more successful and attractive, he'll decide she's not good enough. She doesn't dare accept his feelings. Yet he keeps expressing his sincerity, and over nearly a year, he paints a beautiful romance, becoming part of her life. She finds light when she looks up, and his shadow when she looks down.
When the series they filmed together airs, Peng Yue, the female lead, and Lin Youtian's company want to promote the two as a couple. He wants to refuse, but he doesn't have enough clout to do so and can only put up with it. Meanwhile, his rival's team tries to sabotage him, flooding the internet with slander. He panics, afraid Yuan Xin will be upset. Instead, she laughs at him for being so thin-skinned, saying this is something everyone has to endure if they want to become famous. He thinks she's being sarcastic, and another rift opens between them.
Yan Yue, the senior Yuan Xin had secretly loved for years without success, finally comes to his senses and turns back to her, only to discover that she's already entangled with someone else. His mother regrets it too, since she had always considered Yuan Xin a future daughter-in-law. He can't stand it and decides she must be fickle. Just then, someone writes a news story claiming Yuan Xin used Yan Yue and then hooked up with Lin Youtian. Someone tells Yan Yue, but he does nothing, letting them publish it. Once the story comes out, Yuan Xin and Lin Youtian are both in a panic, and online trolls show them no mercy.
Lin Youtian's company's PR team steps in to manage the situation and tells him to distance himself from Yuan Xin. He refuses to abandon her now. She thinks it's better to save one of them than have them both go down...
