I don’t understand his interest in Yoohyeon. Someone who read the novel could spoil?

I didn’t read the novel but based on the past, he really loves Ina and Yoohyeon reminds him of Ina, unfortunately Hyeonshin took Ina but since Yoohyeon is there kid ig it’s like he’s not as off limits? But not in a sexual way

Nah there is no way this go that route. I didn’t even think about that because this is the type of manhwa that is straight as an arrow. They don’t have the guts to have a sexually ambiguous character and even less to add a lgbt+ couple

goes*

in what I understand is he protects yoohyeon because he looks like Ina whom he loves, he also teach him how to use his power

Makes sense. He probably cares about him like an uncle or something like that

Are you guys blind ?
There is clearly something more in there.
Since this is a shoujo it's not gonna be explicit like in other mangas/ manhwas/ manhuas.
But he clearly is loving Yoohyeon
