My Mortal Enemy Actually Wants Me to Fall in Love with Him

Apocalyptic slash scientist × time traveler He Heng is the second-in-command of the institute. In 2200, the earth's environment was seriously damaged and human survival was threatened. He had to take up the heavy responsibility and explore ways to save the earth amidst the worries. When he went out to investigate and accidentally ended up on a deserted island, He Heng met "Friday". He lacked awareness of human emotions and had many ridiculous stories with He Heng on the island. After returning to the institute, the mysteries about the west are gradually solved, and the secrets of the end of the world are revealed, including selfishness, regret, and redemption... "Over here," Bliss said. He Heng was confused, but he didn't find anything. "How do you know?" "Actually, is it possible that I already knew you before I met you?" Lightning protection: The deputy CP has a clone, who is no different from ordinary people except for his tragic life experience, and he is the big villain. One of the protagonists is an alien staff member (a numbered person). The two had known each other for a long time in another time and space, but He Heng died during a mission. Bliss traveled through time and space to help him avoid his original trajectory. He had long since lost his life in the constant alternation of time and space, so he didn't want He Heng to have a good impression of him. For convenience, Bliss killed himself in this time and space. First meeting: "You are a good fighter. Come back to the research institute with me?" Bliss came with a mission this time. He wanted to bring back the person numbered A006. It was the person in front of him - his old enemy, who was left on Earth because he committed a crime. "Okay, fall in love with me, and I'll do whatever you want."
