This is technically an isekai but the MC is not the one who transmigrated. I believe it was her maid/nanny that did. The MC was probably the villainess in the OG!story and the nanny wanted to change that.
This one is an isekai but whether the MC died or was just transmigrated remains to be seen. Though MC was 9 in her original world she's now 5ish
This one is special because technically there's two FL. The ancestor and the descendant, The A!FL takes over the D!FL's body when she's harmed/almost killed by her family but later the two do separate into their own bodies. So it's a honorary member
Another special one. MC has an ability where she swaps places with her future self. Most of the POV is the younger MC except when she switches then we see both
This one is another special one. MC did live at least 15+ years but she did it as a mouse, it's not until she's been reborn and breaks her curse that she changes into a human. I don't think the first life she spent as a mouse should be counted as an adult/growing up especially because animals tend to live really simple/child-like lives.
This is sorta a sad one. MC actually died as a child in her first life, then she's reborn a month prior to her death. I will say it's a cute story but the beginning is harsh
This is another honorary one. MC was reborn at some point but her memories of her past life are vague. So when she acts like a child it's genuine and not manipulation
