Bro this gotta be low tier rage bait lmao. Sure I bet shes gonna get a redemption arc, but even if that happens, her sins aren't forgiven.
Also it's not "so obvious" he will fall in love with Hebi, the only obvious thing is that he still finds her attractive, but it's clear that he doesn't like her the same way before.
By the way the manga is progressing, I bet Hebi is going to realize the error of her ways, not a snowball's chance in hell he's gonna fall in love with that snake a 2nd time lmaoo. Cope harder bruh. She's better off trying to nail jell-o to the wall than to fool him again.
