Name please

Mc is a swordsman I think and he explores dungeons with his party who then betrays him by attacking and killing him. Then he goes back into the past and becomes a healer instead (irl there’s like a game system where if they’re chosen they can choose a job and he chose healer instead of his previous job so he can heal himself) but he still learns his previous job skills so he’s like a healer swordsman

**I am just asking around for another person... Do let me know if you guys know its name...Thanks in advance
