The dictionary calls affection "a gentle feeling of fondness or liking". Wikipedia says:
Affection is popularly used to denote a feeling or type of love, amounting to more than goodwill or friendship.
When looking up words for affection on the Korean dictionary, those are what I found, but they all seem to have some slightly different nuance.
정 attachment
다정 kindness, sweetness
인정 empathy
애정 (loving) affection
Does any of them fit the above definition of affection? Or is there perhaps a less loaded word to simply describe the "warm and fuzzy" feeling of closeness to other people, without necessarily amounting to love?
An example sentence would be: "We seem to like each other a lot, but he didn't show me any affection."
