Netorare situations can be avoided in the game under certain conditions. The scenes where you can choose not to witness the NTR events, but they still happen behind the scenes, should not be counted as avoidable.
Unlike "Only Avoidable Netorare", Avoidable Netorare means that there may be unavoidable netorare-like situations in the game.

The tag has been made obsolete in favour of the newly clarified tags Unavoidable Netorare and Completely Avoidable Netorare. Please use these tags, and in the situations where you are not sure which tag to use (for example, because you haven't finished the game), use the generic Netorare tag instead.
