(spoiler warning)
i read the novel until ch104 and I'm not sure what his feelings exactly are, but at the point where I'm at he constantly checks on her and it's very protective, so it's very likely he sort of likes her . And they started kissing a lot (with tongue!)
Also since it's a novel from Suji Kim, i expect this to be story where ml seems cold but actually likes a lot, like Cry said, since author's other work is similar
he likes her a lot but hes really weird ab it
from the novel it said shes the one who brings color into his life? there are some fans that say hes always staring at the sky because it reminds him of her eyes
he also refuses to divorce talia when gareth(?) tells him to marry ayla instead because talias dead. (novel is ongoing so shes probably gonna get resurrected or something so dont worry about it)
also nsfw but theres a scene where talia thinks varkas' sword hilt is hitting her stomach but its really not... #_#

Does he like her or nah? Spoil me pls
