I would say it's Lee Hyunmook who develops feelings first, in a protective, possessive, and distorted emotional sense, because his mind is fractured by the madness of the Abyss. But it will become deeper and more romantic later on. We have a long way to go but it's a great build-up worth the slow burn.
