>>82845850Suki is "like" in the sense of both "I like that food" or "I like that person romantically" It's used commonly for romance specifically because it's an understatement and humility is important. Other ways of expressing love are more direct but also seen as presumptuous and better kept private
Ai is the generic word for romantic attraction and has a dozen forms based on whether it's being used as a noun or a verb, including renai.
Koi is a noun that's synonymous with the noun forms of Ai but considered more casual and less intimate, and is typically used in contexts where there isn't emotional attachment between the speaker and the concept (ie an OL moaning "koi shitai" "I want to fall in love" while drinking alone after work.)
