Kinda wish Jasmine would be his future love interest and not miss you know who

Yeah I think Art's and Jasmine's personalities are much more suited. But I think they will have more of a sibling camaraderie. And I'm fine with this. We also can't forget Art's mental age is a lot older than the elf girl (forgot her name) so she is acting more her age than he is. Just wait till she gets older, she might become more suitable.

Novel ?

Here is the only novel link I could find but I think for most of the chapters I think you have to pay but since its in Korean you may need a translator device or something as it won't auto google translate.
(Tested it myself on a free chapter.)
