Paljae may not instinctively know feelings and emotions, but he certainly knows Ryeong. That part where he looked like a child and tried to hug Ryeong only to realize it's just clothes left and he's alone, I'm sure he felt that the person he loves is about to disappear. He knows he went too far, that's why he backpedaled and was content with just having his feelings acknowledged, nevermind reciprocated. He was truly hurt when his feelings got disregarded by the person who has it.
He may have just recently found the name to describe it, but all along, love has been what it is.
