I think they dont gonna be happy because they die young and reicarnated again and again. And when they reicarnated they falling love again but the destiny separated, its like the infinte symbol.
I like this webtoon is refreshing and the characters are unique but I don't like a brother that brake everything jaja he make me laugh when he pop of nowhere with a punch or a kick jaja
The manga never gonna end if they become couple because each day of them is gonna be hilarious and funny author please make tomo say yes
