even though the main point of the visual novel is netorase there's a possibility that it will end in netorare where eimi got taken by the bull,also this was design for people that want a complete lose in netorase story
the ntr point can be obtained by choosing the special pink colored choices,so what's the different between this and just choosing a single choice at the end of traditional vn to determine the ending? by getting an ntr point in one chapter it will unlock a special event in the next chapter,what kind of special event?
it will be event that will humanize and grounded the bulls with developing "romance" event to be something of potential love interest for eimi and not just some guy you hired to fuck eimi, by getting more and more point eimi will grow a genuine relationship with them and since eimi and kenichi will have a loving relationship throughout the story it will be a whiplash if suddenly eimi choose the bull at the end of the story if we not do this
and for the special event what kind of things you will get from it,obviously special CGs and more "romantic" kind of interaction
it will be a total lose where not only the bulls taking eimi's body from kenichi but also her heart,well eimi will always love kenichi even in the ntr ending she just chose to stay with the bull for the moment (most the time)
netorase will be the normal state,so you can only get netorare ending if you collect all the special event
this only happen in 3 main route,genzo,jerome,and yuki even though ryosuke have tracker he will not give any point
