Scum Gong Regret Recs?

Does anybody have good angst recs? Like ML groveling after misunderstanding MC and hurting him, MC used as substitute(!), wholeass regret arc, ML hurting for hurting MC, hated MC who is actually a cutie bean and everyone realizing it stuff. I need pain and angst, but the satisfying kind🥺
Also would love some good time travel or dimension travel recs if nothing comes to mind for scum gong regret kinda ones🙈
I would recommend one myself to get it started but I haven’t found a good one myself yet (just got started in manhwas after leaving the danmei/BL novel space for the visual elements)

Hope this is the right place to ask, thank you all in advance💕
