Looking for a manhwa

I don’t remember if it was a esper / guide verse or something . But the MC used to like the ML but ML was in a relationship with a female . The MC then dies during a mission . After his death he goes back in time . The MC decides to redeem himself as he was awful to ML in his past . So he decides to help the ML and female be together . The MC tries to become a better person himself . The last chapter before season finale were basically the MC being a hostage in an amusement park . Help me find it
