If you leave Leslie out of it, under the strict definition of netori only Candy counts since she is in a formal relationship and starts cheating after seeing the MC's dick. There are other women MC is gonna seduce that are married but none of those have content yet. Everyone else is single.
As a side note, the reason that people disagree on what NTR is due to the definition not being a direct equivalent for cuckoldry. Netorare roughly translates to "having something precious stolen" with the "something" part meaning both a tangible and non-tangible connection to a person, the actual word doesn't translate in to English properly; this is why a parent fucking someone bulling their child is considered NTR according to the Japanese even though the parent and child aren't in a sexual relationship.
Thats why there is a distinction between netorare and netori, one is where you are meant to project on the the person having something stolen and the other where you are the theif. People conflate NTR with direct physical cuckoldry since it's the most common expression of it but it's not required according to the definition.
Source: know multiple languages and these type of translation issues come up often.
EDIT:
Fun fact, this is why some asian language content has absoulte word salad names, think "Super Happy Family Funtime Adventure" or something of the like, the actual name in the native tongue doesn't sound that long but due to the exact word defintion not being a direct equilvent translators will pile on multiple words with simliar but slightly different meanings to get the message across.
. Fingers crossed she does well in the voting brackets next time.
