Even Ilay whose a bit of an enigma bec we rarely see things from his POV, if at all (I read the novel), the way he changed bec of Taeui felt just right (though it did took a really really long time)
And Shinje for me have always felt a kinship with Yugeon bec of their shared connection with Almuten.w
But what about Nakwon and Mokhwa? I understand Nakwon becoming interested or intrigued at Mokhwa especially for his peculiar tendency of being blindly loyal and so starved for affection that he'd cling onto someone who shows him the slightest bit of kindness even if that was the one who hurt him in the first place... I mean, that's also what draw Ilay towards Taeui (bec Taeui was someone who is capable of not completely hating Ilay no matter what he does, and Ilay does whatever he wants).
But how did Nakwon's feelings for Mokhwa became so intense and deep? Is there more to Nakwon that were not seeing which will be revealed in S2?
