[From the 21St Century] I Disappear Like Fireworks

[The 18-year-old me hopes that the 38-year-old me will die soon] Original male protagonist, OOC warning, belongs to BL content, a bunch of private settings, the male protagonist does not have a designated official partner, you can randomly bump into each other Han Guang and the male protagonist are set up to have a relationship with their ex-boyfriends. They are very crazy (it is assumed that Han Guang does not have a girlfriend, and the timeline of their relationship happened when they were 19 years old) Intention: Let's become a ship together, control the course and move forward forever.
