YA'LL CALM DOWN there's alternate endings, meaning that we'll get different endgames for the mc. There's no definite maingame but from what I suspect from the novel (and given spoilers) Hina was the main end
They could've made the ML a completely unrelated person from her 1st life. Istg that remorseful-pathetic brother dude ain't my type. Hesarose is the only solace I'm comfortable with or a whole new character that helps with the MC's healing journey
Remember how this started out from just simple fan simping for her favorite character? TT
