Does this have novel?
Yes there is, personally I like the novel a lot too but the manhwa is better at capturing Kaelus and Hestia romance development (probably because they choose a really great artist to adapt the novel into manhwa). If you like the manhwa I would say give the novel a shot too (=・ω・=)
Do you have the link to the novel please? I think I read it a while back but idk where to find it now.
