Once I traveled through time and met the heroine when I was a child, I wanted to treat her coldly, but I couldn't help but couldn't stand the heroine's active advances. But what does it mean to be hot and cold? ? ? What about the heroine who was promised to be cool and not to eat fireworks? What's going on with this yandere's character? Can the butterfly effect brought about by time travel be reversed and break the original plot? Xun'er attacks!
