Travel Back to Your Parents' 18-Year-Old Age with Your Rival

The time travel triggered the two to dig out a time capsule from 1998 in the school's abandoned auditorium, which contained an unsent letter from their parents and two old school badges. A thunderstorm occurs when you touch the school badge + read the letter, and you are transported to the same day when your parents turned 18. Travel rules 1. You can only stay for 30 days, and the flow of time is different from that in modern society (only 1 hour in modern society). 2. You cannot directly tell your parents that you are their future child (it will trigger "time backlash" and disappear early). 3. The parents must fall in love (produce a "heartbeat event"), otherwise the two will not be able to return to modern times. 4. Among the belongings, the mobile phone cannot be used, but an MP3 player with old songs can be played (it has become an important emotional prop). Time travel to 1998, a small southern town, BP machines, tapes, video halls, and 50-cent spicy strips at the school gate. My parents went to the same high school but disliked each other.
