even if you don't agree, you should be able to make sense of what they're saying.
let me dumb it down for you....
BASICALLY SHE HAS LIVED SO MANY LIVES AS COUNTLESS OF GENDERS OLDER THEN 20 AND SHE FELL IN LOVE WITH A CHILDDDD.
she starting catching feelings in her 18th life when he was a 9yo.. Does this make sense?
if it doesn't please consult a doctor! ASAP

It was literally explained tho.
1. Age: she's still a 12 years old. This is not a "I am a 1000 yr old being who looks like a child" trope. She's a real, normal human being, who can be immature but has figments of her past lives. It doesn't equate at all to her being an adult in a child's body. It just makes her more mature than a child her age because she remembers horrible things (just like a normal child who had a trauma and is more mature in real life).
She is Ban Jieum with figments of the past and not Life 1 + Life 2 + ... + Young Jun + Ban Jieum
2. Interest: If you read the story, she literally explained why she fell in love with him who was not so special.
Smelling pedophilia, havent she known him ever since they were kids? Whilst having an adult mind? Yet she still dated him later on when he grew up? Also weird that a person who has lived nineteen lives suddenly becomes attached to a kid boy whom she met and that kid wasnt even all that, boring ass personality. Guess in her prevs life she hasnt met anyone that memorable, lol????lmfao weird story. Fuckass fl, boring ass ml too.
