The Counterattack of a Time-Traveling Female Partner

I Beg the Male Protagonist to Be Reborn and Still Help the Female Protagonist🥺

The male protagonist was a genius alchemist before time travel, but he was killed by the female protagonist and his hands were disabled. After his rebirth, he gradually showed his genius in alchemy, but he remained anonymous and was protected by the female protagonist as a support. I really want to see this 🥺
