Christopher and Richard are a couple. Their relationship is somehow similar to that of Taeui and Ilay, no label yet very intimate....and they're childhood friends( If I remember correctly). And no, Taeui isn't attracted to Chris...he just find him pretty/ beautiful.
I got spoiler here and there. Read that richard seems to be sleeping around with other girls as well. If so, this is very disrespectful. No wonder chris heart swayed and is attracted to taeui. Since I have not read the novel, I do not know how richard and chris relationship is like. Maybe they are just sleeping with each other but not emotionally connected.
I did not read the novel and wonder who is christopher? Is richard and christopher an item? Apparently, Taeui seems attracted to chris.
