@Kimdokja I like heart Mad hatter feels like he's trying to use soyoon to get over his trauma (you know like "you and i went through the same thing lest lick each other's wounds") and the twins see her as a mother figure
There are several extra stories for the novel 1 where what if mad hatter was ML 2 what happens after from twins poverty 3 soyoon returns to her world and goes to see "alice" (can't remember her real name)
@Orang yes unfortunately so But luckily for you there's a what if side story for mad hatter Look in novel buddy "winter rabbit in wonderland" Full story is in there plus 3 what ifs
