Boyfriend dies in car crash and girlfriend goes back in time to save him [fully lost]

Hi I’m an account I remembered this YouTube movie trailer that I saw around 2021 or 2022 in the trailer A African-American woman accidentally goes back in time to save her African-American boyfriend I think there was one seen in the trailer where the woman gives her boyfriend flowers I think the type of flowers where roses i’ve looked everywhere. I’ve searched on Google I went on IMDB but I couldn’t find the movie anywhere I found movies similar to the plot, but not the exact plot I found a movie similar to this called “If I Stay” but the girlfriend gets into the crash not the boyfriend.
