Personal Fave

MC spawns in dungeon and immediately dies to a trap. When his teammates managed to defeat the world boss, he got healed but couldn't teleport to the next stage because he was considered ''dead'' by the system. He starts digging like crazy and acquires dirt skills and it's basically minecraft from then on. He only does basic stuff like farming and carving but it eventually snowballs into saving the world.

FL is living with her abusive dad & brothers until she dies and reincarnates into an Otome game with the same family dynamic. She's a replacement for the duke's missing daughter and male leads hate her for it. They all regret when FL starts to defend herself and show how abusive they've been over the years.
Worse? she's the villainess who dies after the smallest mistakes and everybody is out to get her.
