Enigma

I'm looking for a manhwa where the ml goes temporarily blind after going to the battlefield. It's not counts maid and that's the only temporarily blind ml manhwa I can find. It's been a few years since I read it so any help is appreciated. Thank you!

Basically its a manhwa where the guy goes back to the past and stwrts pursuing fl but fl is a reincarnator who wants ml to be with ogfl despite having feelings with ml. Ml is blonde, fl has light brown hair, og fl as red hair.
