• Protagonist: Hu Yidao, Hu Yifei's distant cousin. The name has a contrasting sense of charlatanism and comedy. On the outside, he is a handsome and gentle brother next door, but on the inside, he is a "guardian time traveler" who knows all the plots.
• Core CP: Hu Yidao × Lin Wanyu. This was a "destined accident" - Hu Yidao initially just wanted to protect this beautiful girl from all harm, but as he got along day and night, he discovered that she was the meaning of his time travel.
• Key premise: Lu Zhanbo's feelings for Wan Yu will be gently reshaped into "a beautiful but misplaced first love" in this story. Zhanbo will have his own, more suitable growth line and emotional destination.
