Manga/Manwha Title Recs Plz

Hello! Does anyone have titles of manga or manwha where the main characters transmigrates or reborn (anything of that nature even just like going into a video game or something idk) and actively goes after the 2nd lead in the original story?

I feel like I’ve seen one before but can’t remember the name!

Thank u xxヾ(❀╹◡╹)ﾉ~
