Netorare (寝取られ, NTR) is a genre tag where one partner is 'taken' by another person, typically involving infidelity or cuckolding. The term literally means 'to have one's partner stolen.' NTR is a complex genre with its own tropes: the emotional anguish of the betrayed partner, the seduction/taking of the unfaithful partner, and the voyeuristic element. The genre ranges from dark drama to fetish content. Related tags include 'cheating,' 'mind break,' and 'dark skin.' NTR is one of the most polarizing tags in doujinshi — readers either love it or actively avoid it.

Collar (首輪, kubiwa) is a costume/accessory tag indicating characters wearing collars, often in a BDSM context. Collars symbolize ownership or submission in kink scenarios. The tag covers both decorative collars and functional bondage collars. It frequently appears alongside 'bondage,' 'femdom,' and 'pet play.'

Cheating (浮気, uwaki) refers to infidelity or adultery in doujinshi narratives. Unlike 'netorare' which focuses on the victim's perspective, 'cheating' can be told from any perspective. The tag covers both emotional and physical infidelity. It frequently appears alongside 'netorare,' 'milf,' and 'married woman.'
